From e40b61fb6bd2e0ed2dc4799096fcf4c828c28d6d Mon Sep 17 00:00:00 2001 From: Jason Riedy Date: Fri, 2 Dec 2005 15:08:28 -0800 Subject: [PATCH] Add compat/setenv.c, use in git.c. There is no setenv() in Solaris 5.8. The trivial calls to setenv() were replaced by putenv() in a much earlier patch, but setenv() was used again in git.c. This patch just adds a compat/setenv.c. The rule for building git$(X) also needs to include compat. objects and compiler flags. Those are now in makefile vars COMPAT_OBJS and COMPAT_CFLAGS. Signed-off-by: E.
