The variable + is assigned the specified value only if that variable is not already + defined. + +* Make defines a new variable, "CURDIR", to contain the current working + directory (after the -C option, if any, has been processed). + Modifying this variable has no effect on the operation of make. + +* Make defines a new default RCS rule, for new-style master file + storage: ``% :: RCS/%'' (note no ``,v'' suffix). + + Make defines new default rules for DOS-style C++ file naming + conventions, with ``.cpp'' suffixes. All the same rules as for + ``.cc'' and ``.C'' suffixes are provided, along with LINK.cpp and + COMPILE.cpp macros (which default to the same value as LINK.cc and + COMPILE.cc). Note CPPFLAGS is still C preprocessor flags! You should + use CXXFLAGS to change C++ compiler flags. + +* A new feature, "target-specific variable values", has been added. + This is a large change so please see the appropriate sections of the + manual for full details. Briefly, syntax like this: + + TARGET: VARIABLE = VALUE + + defines VARIABLE as VALUE within the context of TARGET. This is + similar to SunOS make's "TARGET := VARIABLE = VALUE" feature. Note + that the assignment may be of any type, not just recursive, and that + the override keyword is available. + + COMPATIBILITY: This new syntax means that if you have any rules where + the first or second dependency has an equal sign (=) in its name, + you'll have to escape them with a backslash: "foo : bar\=baz". + Further, if you have any dependencies which already contain "\=", + you'll have to escape both of them: "foo : bar\\\=baz". + +* A new appendix listing the most common error and warning messages + generated by GNU make, with some explanation, has been added to the + GNU make User's Manual. + +* Updates to the GNU make Customs library support (see README.customs). + +* Updates to the Windows 95/NT port from Rob Tulloh (see README.W32), + and to the DOS port from Eli Zaretski (see README.DOS).
