 It's not really uglified. Microsoft CRT is pretty consistent in prepending
underscores to POSIX/Unix98/anything-but-ANSI-C functions. This is
certainly annoying at times but it makes its kind of sense.

 I want configure to work with both mingw32 and cygwin and one of them (I
think it was cygwin but I'm not 100% sure; I can recheck it though) has
only _snprintf but not snprintf.

 It only does this if _POSIX is defined and __STDC__ is *not* defined. And
the latter must always be defined in practice so, no, it doesn't really do
it.

 Thanks anyhow for your suggestions!
