My attempt at mounting /MinGW failed, so I just made a symbolic link. So
now /MinGW points to /cygdrive/c/MinGW. /MinGW/bin comes before
everything else in my PATH in /etc/profile.

$ gcc -v

I think it wants to be friends with me. ;) It looks fine to me. Right?

$ `pkg-config gtkmm-2.0 --cflags --libs`
bash: -IC:/cygwin/include/gtkmm-2.0: No such file or directory

Ehh, not good. Why?

$ g++ test.cpp -o test `pkg-config gtkmm-2.0 --cflags --libs`
C:/cygwin/lib/libstdc++.a(vterminate.o)(.text+0xf1): undefined reference
to `_impure_ptr'
C:/cygwin/lib/libstdc++.a(vterminate.o)(.text+0x136): undefined
reference to `_impure_ptr'
C:/cygwin/lib/libstdc++.a(cxa_demangle.o)(.text+0x4ae7): undefined
reference to `_impure_ptr'
C:/cygwin/lib/libstdc++.a(cxa_demangle.o)(.text+0x4b0f): undefined
reference to `_impure_ptr'

Ok, still the same linking to the wrong stdlibc++ problem. /MinGW/bin is
really the very first thing in "echo $PATH".
