Michael J Gruber noticed that connection via the git:// protocol no longer worked after a recent header clean-up. This was caused by funny interaction of few gotchas. First, a necessary definition #define DEFAULT_GIT_PORT 9418 was made invisible to a place where const char *port = STR(DEFAULT_GIT_PORT); was expecting to turn the integer into "9418" with a clever STR() macro, and ended up stringifying it to const char *port = "DEFAULT_GIT_PORT"; without giving any chance to compilers to notice such a mistake.
