-MT just links with the multi threaded vc++ libs, see win32.mak
in the Platform SDK and the headers for docs on this.

--subsystem windows is the ld.exe command line option.

This can be passed to ld.exe (the linker) by gcc.exe (the compiler driver) by putting
-Wl,--subsystem,windows on the gcc command line
note the use of , instead of space.

the best ? option to use is -mwindows	(libuser32.a) 	(libgui32.a)
this will automatically pass --subsystem windows -luser32 and -lgui32
to the linker.

Geoff, could we get this changed to -windows
-m gets misread by cpp as a processor spec, which
makes -mwindows unless for -I options in specs.

Use the source luke. ;^)
