* read.c (eval): [SV 41677] Correct test for TAB vs. 8 spaces.

2014-07-07T07:43:57Z

* GNUMAKEFLAGS: Remove -O so it passes in NO_OUTPUT_SYNC mode.

2013-10-19T16:05:58Z

Fix portability issues for Guile 1.8.

2013-09-30T14:56:20Z

Solaris /bin/sh can't handle multiple options ("-e -c").

2013-09-30T04:12:18Z

Reset GNUMAKEFLAGS after parsing.

2013-09-29T17:15:00Z

If we don't do this we'll continually add flags on recursion. This is mainly for users to set in their environment before invoking make.

Enhance the output sync mode.

2013-09-12T08:07:52Z

Create a new file, output.c, and collect functions that generate output there. We introduce a new global context specifying where output should go (to stdout or to a sync file), and the lowest level output generator chooses where to write output based on that context. This allows us to set the context globally, and all operations that write output (including functions like $(info ...) etc.) will use it. Removed the "--trace=dir" capability. It was too confusing. If you have directory tracking enabled then output sync will print the enter/leave message for each synchronized block. If you don't want that, disable directory tracking.

Fix regression tests after MAKEFLAGS enhancements.

2013-05-22T11:51:46Z

Add a new variable: GNUMAKEFLAGS

2013-05-13T06:48:18Z

This allows you to write portable makefiles that set GNU make-specific command line options in the environment or makefile: add them to GNUMAKEFLAGS instead of MAKEFLAGS and they will be seen by GNU make but ignored by other implementations of make.

Use level o_env_override for MAKEFLAGS so it's reset even with -e.
