  Nope, but you'd get a better idea if you try running

g++ -E -mno-cygwin -ansi -DGCC3X -DLINUX -DINLINE=inline -fno-default-inline
 -W -Wno-deprecated -fomit-frame-pointer -ffast-math -mcpu=pentium4 -march=p
entium4 -mfpmath=sse -O2 -I./ -o xyz.no-cyg.i xyz.cpp -v

g++ -E -ansi -DGCC3X -DLINUX -DINLINE=inline -fno-default-inline
 -W -Wno-deprecated -fomit-frame-pointer -ffast-math -mcpu=pentium4 -march=p
entium4 -mfpmath=sse -O2 -I./ -o xyz.cyg.i xyz.cpp -v

at the command line.  Then you'll be able to look through the preprocessed
source files, and get a clearer idea why all those symbols are defined in
the cygwin environment but not the mingw environment; you'll see exactly
what files are including which ones in what order from the #line directives;
and the output from the command lines (because of the '-v') will show you
the different search paths etc. that are passed to the compiler in the two
cases.

    cheers,
