The installer is for mingw32 only. What you're trying to do is to mix 
the cygwin runtime (the cygwin1.dll) with the native win32 runtime 
(MSVCRT.dll), which can lead to unexpected results.

You actually have two choices :

1. If your program does not rely on posix functions, then use my 
installer with either "mingw32-gcc" (http://www/mingw.org) or 
"cygwin-gcc -mno-cygwin". With the -mno-cygwin option, the gcc compiler 
from the cygwin distribution with link against msvcrt instead of the 
cygwin posix layer.

2. If your program relies on posix (unix-like) functions like sockets 
for examples, you'll have to recompile gtkmm against the cygwin runtime. 
Search through the gtkmm mailing list for details.
