Subject: Replace unsetenv() and setenv() with older putenv().
X-Git-Tag: v0.99.6~65^2~1
X-Git-Url: https://git.octo.it/?p=git.git;a=commitdiff_plain;h=e72a7d45dc67afa1328750d401ddd4dbeb2131d9

Replace unsetenv() and setenv() with older putenv().

Solaris 8 doesn't have the newer unsetenv() and setenv()
functions, so replace them with putenv().  The one use of
unsetenv() in fsck-cache.c now sets GIT_ALTERNATE_OBJECT_
DIRECTORIES to the empty string.  Every place that var
is used, NULLs are also replaced with empty strings, so
it's ok.
