Git, C89, and older compilers

[Joshua Juran <jjuran@gmail.com>]

Hello,

I'm porting Git to Lamp (Lamp ain't Mac POSIX), a Unix-like  
environment which runs in classic Mac OS, much like Cygwin.

One of the complications I've run into is that Metrowerks C 2.4.1  
(released in 2001) doesn't support some of the constructs git uses,  
such as initializing an aggregate's member with the address of a  
local variable, illustrated by the patch below:

diff --git a/builtin-commit.c b/builtin-commit.c
index 46e649c..8b98547 100644
--- a/builtin-commit.c
+++ b/builtin-commit.c
@@ -605,7 +605,8 @@ static int prepare_to_commit(const char  
*index_file, const c

         if (use_editor) {
                 char index[PATH_MAX];
-               const char *env[2] = { index, NULL };
+               const char *env[2] = { NULL, NULL };
+               env[0] = index;
                 snprintf(index, sizeof(index), "GIT_INDEX_FILE=%s",  
index_file);
                 if (launch_editor(git_path(commit_editmsg), NULL,  
env)) {
                         fprintf(stderr,

Is git intended to compile on a C89 compiler?  In any case, if I  
produce a complete set of patches, will they be applied?
