2.573.2.3 is the version number of setup.exe, 1.5.25-15 is the version
number of the cygwin library.

I bet the obvious reason I'm thinking of isn't the one you're thinking
of. Your glib.h almost certainly has DOS style line endings, but the
header is on a UNIX mount. This means that the compiler sees a '\r'
after the \, which is NOT valid code.
You don't say where your glib.h came from, but I'd wager it's not from
the cygwin package. If you're compiling a cygwin program, you need to
install cygwin's glib2 package, and the matching glib2-devel package.
Had you *attached* the output of cygcheck -svr as requested here:

It would have been easy to confirm that you were not using the cygwin
packaged glib.
