After great gobs of my time trying to get a C++ console program to compile
under cygwin using -mno-cygwin, I found a solution (workaround).
Check out the link:
http://www.cse.buffalo.edu/~dafiden/cygwin/

Here is a transcription of the page:


Getting cygwin to compile C++ using -mno-cygwin
Install cygwin as normal.

Install the extra mingw headers and libraries from the
gcc-2.95.2-mingw-extra.tar.gz file.

Here's a link to a file I modified for convenience:
gcc-2.95.2-mingw-extra.tar.gz
(If this doesn't work, or if I find out I'm not allowed to do this ;),
just get the regular gcc-2.95.2-mingw-extra.tar.gz file from here:
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/cygb20/gcc-2.95.2/gcc-2.95.2-mingw-extra.tar.gz
and make the files correspond to the structure defined below).

Setup the gcc-2.95.2-mingw-extra.tar.gz file as follows:

drwxr-xr-x dafiden/unknown   0 2001-11-04 13:35:16 lib/

-rw-r--r-- dafiden/unknown   2797 1999-11-06 20:55:40
usr/include/mingw/_G_config.h

type this:
ln -s /usr/include/g++-3 /usr/include/mingw/g++-3

edit the file:
/lib/gcc-lib/i686-pc-cygwin/2.95.3-5/specs
where it reads:
*libgcc:
%{mno-cygwin: %{mthreads:-lmingwthrd} -lmingw32} -lgcc
%{mno-cygwin:-lmoldname -lmsvcrt}
change it to read:
*libgcc:
%{mno-cygwin: %{mthreads:-lmingwthrd} -lmingw32} -lgcc
%{mno-cygwin:-lmoldname -lmsvcrt -lcrtdll}

You can check to see if it works with a "hello world" c++ program.
type:
g++ -mno-cygwin hello.cpp
a
(You can use my hello.cpp and check for a message with a 5 second sleep
in between)
If it works, "you done good."

I haven't done a lot of programming until recently, so I imagine that
mingw
libstdc++ looks for some DLL stuff in libcrtdll.  Consequently, one needs
to
add that lib to the default specs for g++.
