* maint: update all copyright year number rangesJim Meyering2012-01-011-1/+1
| | | | Run "make update-copyright".
* build: ccache works better without embedded version stringsJim Meyering2011-06-131-0/+1
| | | | | | | | | | | | | * src/Makefile.am: Generate version.c and version.h and put the new symbol in a tiny library to be used by each program. (LDADD): Add the new library. * src/cmp.c (main): Use Version, not PACKAGE_VERSION, so the .o file does not change with each commit-derived version increment. * src/diff.c (main): Likewise. * src/diff3.c (main): Likewise. * src/sdiff.c (main): Likewise. * src/system.h: Include "version.h". * .gitignore: Add version.[ch]
* maint: remove all uses of vfork: use fork insteadJim Meyering2011-01-241-9/+0
| | | | | | | | | | | | | Our use of vfork now provokes warnings from gcc-4.6.0. Also, vfork is no longer even specified by POSIX.1-2008. * src/diff3.c (read_diff): Change each use of vfork to "fork". Remove #ifdef'd code. * src/util.c (begin_output, finish_output): Likewise. * src/sdiff.c (cleanup, main, edit): Likewise. (handler_index_of_SIGPIPE): Remove now-unused definition. * src/system.h: Don't include <vfork.h>. (vfork): Remove definition. * ms/config.site: Remove reference to vfork cache variable.
