I would, instead, suggest this elegant hack:

zx2c4 at thinkpad ~ $ cat a.c
int main(int argc, char *argv[])
{
        printf("git's main\n");
}
zx2c4 at thinkpad ~ $ cat b.c
#define main git_http_backend_main
#include "a.c"
#undef main

int main(int argc, char *argv[])
{
        printf("cgit's main\n");
        git_http_backend_main(argc, argv);
}
zx2c4 at thinkpad ~ $ ./a.out
cgit's main
git's main


This way, in fact, we don't even need to use the main function, if it
turns out we could benefit from accessing various static functions.
