I am sorry, it seems my messages wasn't clear enough.  The problem is
not related to the compiler (I got the same results with gcc 3.1 and
3.2).  It is related to changes made in mingw-runtime between version
2.2 and 2.3.  With mingw-runtime 2.2, Emacs compiles and run OOTB.
With runtime 2.3 and 2.4, Emacs compiles OOTB, but fails at execution
time with random errors, because of invalid data read.

Here is an excerpt of the change log of mingw-runtime 2.3, which I
think is related to IO mode change:

2002-10-19  Danny Smith  

	* crt1.c: Define new macro __IN_MINGW_RUNTIME before including
	stdlib.h.
	Define WIN32_MEAN_AND_LEAN before including windows.h
	* include/stdlib.h (_fmode): Protect declaration as dllimported
	variable with __IN_MINGW_RUNTIME.

2002-10-19  Igor Pechtchanski  

	* crt1.c: Include stdlib.h.

2002-10-19  Danny Smith

	(MINGW_OBJS): Add txtmode.o.
	(SRCDIST_FILES): Add txtmode.c binmode.c.
	crt1.c: Don't include fcntrl.h, stdlib.h.
	(_fmode): Declare, without dllimport attribute.
	(__p__fmode): Declare access function for dll's _fmode.
	(_mingw32_init_fmode): Sync dll _fmode with staticly linked
	_fmode for app.
	* txtmode.c: New file.
	* binmode.c: New file.
	* samples/fmode/test2.c: New file.
