Heh. Then what on earth is it supposed to do when it tries to look up a
password and there's no such thing as /etc/passwd and no such library function
as getpwent?

See, with -mno-cygwin, you really get what you're asking for: NO cygwin!

So, no /etc/passwd, no getpwent, no struct passwd, no uids or gids, nothing
posix-y at all. You have a logical problem in your design here: you want to
use cygwin features, yet you want to use them without cygwin....

Corinna, you missed the mno-cygwin flag I think? I wouldn't expect to find
all these things in mingw headers. There's that bug in the shared 'gcc'
driver that still allows cygwin's /usr/include in the default search path with
-mno-cygwin, which is why pwd.h is even found, but then all the necessary
types (uid_t, gid_t etc) in sys/types.h are different because the correct
(mingw) include/sys subdir is chosen.
cheers,
