i tried also to to use the new autotools, but I have installed cygwin with
DOS line endings support, thus it failed to make because of "CRLF/LF errors"
in genrated Makefiles ... but that doesn't matter because when I added to
the three $(CC)* linking commands the -mdll option it linked the DLLs
without problem.

It is not needed when you use your programs compiled with cygwin glib just
inside the cygwin environment and have it installed the "unix way". But
once you decide to package your program with cygwin runtime and all other
required libraries it needs, you will need the DllMain to find the path
where glib/pango/gtk+ have its files. Exactly like you need it when
compiling with mingw or msvc.

Yes, new gcc is able to export the variables without requiring to use
dllexport, but older version require it, so it is clever to have it there
when compiling DLLs.

Yes, it seemds, that this change is also required. Same probably for
mingw.
