Subject: Define compat version of mkdtemp for systems lacking it
X-Git-Tag: v1.5.4-rc0~292^2~14
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=ca5bb5d5390e4ec709ca3e11c451c58a836d4ee6;p=git.git

Define compat version of mkdtemp for systems lacking it

Solaris 9 doesn't have mkdtemp() so we need to emulate it for the
rsync transport implementation.  Since Solaris 9 is lacking this
function we can also reasonably assume it is not available on
Solaris 8 either.  The new Makfile definition NO_MKDTEMP can be
set to enable the git compat version.
