I don't have any experience with autotools at all. However, here is what I
found out on OS X Mavericks (10.9.5):
1.) In config.mak.uname, line 103, "NO_STRLCPY = YesPlease" is set for some old
OS X version. However, it looks like these settings have no impact at all.
2.) In configure.ac, line 1010, the AC_CHECK_FUNC macros (via GIT_CHECK_FUNC)
is used to detect strlcpy. That detection fails on OS X Mavericks.
3.) I tried to use "AC_CHECK_DECLS" to detect strlcpy declarations on OS X and
this works.
Can you give me a few hints how to debug this further? Why do have the values
in config.mak.uname no impact? My idea was to detect OS X Mavericks there and
unset NO_STRLCPY. Could that work?
Thanks,
Lars
