Commit 5ee2fe777c41d9ad9e7eb9fece56fe21f830c5cd

Add a GIT_PATH_MAX constant The PATH_MAX symbol is often, but not always, defined in the <limits.h> header. In particular, on cygwin you need to include this header to avoid a compilation error. However, some systems define PATH_MAX to be something as small as 256, which POSIX is happy to allow, while others allow much larger values. In general it can vary from one filesystem to another. In order to avoid the vagaries of different systems, define our own symbol. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
