* dir.c: WIN32 does not support inode. For now, fully qualified pathname along with st_mtime will be keys for files. Fixed problem where vpath can be confused when files are added to a directory after the directory has already been read in. The code now attempts to reread the directory if it discovers that the datestamp on the directory has changed since it was cached by make. This problem only seems to occur on WIN32 right now so it is lumped under port #ifdef WIN32. * function.c: WIN32: call subproc library (CreateProcess()) instead of fork/exec. * job.c: WIN32: Added the code to do fork/exec/waitpid style processing on WIN32 systems via calls to subproc library. * main.c: WIN32: Several things added here. First, there is code for dealing with PATH and SHELL defaults. Make tries to figure out if the user has %PATH% set in the environment and sets it to %Path% if it is not set already. Make also looks to see if sh.exe is anywhere to be found. Code path through job.c will change based on existence of a working Bourne shell. The checking for default shell is done twice: once before makefiles are read in and again after. Fall back to MSDOS style execution mode if no sh.exe is found. Also added some debug support that allows user to pause make with -D switch and attach a debugger. This is especially useful for debugging recursive calls to make where problems appear only in the sub-make. * make.h: WIN32: A few macros and header files for WIN32 support. * misc.c: WIN32: Added a function end_of_token_w32() to assist in parsing code in read.c. * read.c: WIN32: Fixes similar to MSDOS which allow colon to appear in filenames. Use of colon in filenames would otherwise confuse make. * remake.c: WIN32: Added include of io.h to eliminate compiler warnings. Added some code to default LIBDIR if it is not set on WIN32. * variable.c: WIN32: Added support for detecting Path/PATH and converting them to semicolon separated lists for make's internal use. New function sync_Path_environment() which is called in job.c and function.c before creating a new process. Caller must set Path in environment since we don't have fork() to do this for us. * vpath.c: WIN32: Added detection for filenames containing forward or backward slashes. * NMakefile: WIN32: Visual C compatible makefile for use with nmake. Use this to build GNU make the first time on Windows NT or Windows 95. * README.WIN32: WIN32: Contains some helpful notes. * build_w32.bat: WIN32: If you don't like nmake, use this the first time you build GNU make on Windows NT or Windows 95. * config.h.WIN32: WIN32 version of config.h * subproc.bat: WIN32: A bat file used to build the subproc library from the top-level NMakefile. Needed because WIndows 95 (nmake) doesn't allow you to cd in a make rule. * w32/include/dirent.h * w32/compat/dirent.c: WIN32: opendir, readdir, closedir, etc. * w32/include/pathstuff.h: WIN32: used by files needed functions defined in pathstuff.c (prototypes). * w32/include/sub_proc.h: WIN32: prototypes for subproc.lib functions. * w32/include/w32err.h: WIN32: prototypes for w32err.c. * w32/pathstuff.c: WIN32: File and Path/Path conversion functions. * w32/subproc/build.bat: WIN32: build script for subproc library if you don't wish to use nmake. * w32/subproc/NMakefile: WIN32: Visual C compatible makefile for use with nmake. Used to build subproc library. * w32/subproc/misc.c: WIN32: subproc library support code * w32/subproc/proc.h: WIN32: subproc library support code * w32/subproc/sub_proc.c: WIN32: subproc library source code * w32/subproc/w32err.c: WIN32: subproc library support code

+Port of GNU make to Windows NT and Windows 95
+Builds natively with MSVC 2.x or MSVC 4.x compilers.
+
+To build with nmake on Windows NT or Windows 95:
+
+ 1. Make sure cl.exe is in your %Path%. Example:
+
+ set Path=%Path%;c:/msdev/bin
+
+ 2. Make sure %include% is set to msvc include directory. Example:
+
+ set include=c:/msdev/include
+
+ 3. Make sure %lib% is set to msvc lib directory. Example:
+
+ set lib=c:/msdev/lib
+
+ 4. nmake /f NMakefile
+
+
+There is a bat file (build_w32.bat) for folks who have fear of nmake.
+
+Outputs:
+
+ WinDebug/make.exe
+ WinRel/make.exe
+
+Notes:
+
+ This port prefers you have a working sh.exe somewhere on your
+ system. If you don't have sh.exe, port falls back to
+ MSDOS mode for launching programs (via a batch file).
+ The MSDOS mode style execution has not been tested too
+ carefully though (I use GNU bash as sh.exe).
+
+ I verified all functionality with a slightly modified version
+ of make-test-0.4.5 (modifications to get test suite to run
+ on Windows NT). All tests pass in an environment that includes
+ sh.exe.
+
+ I did not provide a Visual C project file with this port as
+ the project file would not be considered freely distributable
+ (or so I think). It is easy enough to create one though if
+ you know how to use Visual C.
+
+ I build the program statically to avoid problems locating DLL's
+ on machines that may not have MSVC runtime installed. If you
+ prefer, you can change make to build with shared libraries by
+ changing /MT to /MD in the NMakefile (or build_w32.bat).
