Problem with gcc -mno-cygwin?

[Charles Wilson]

So I'm trying to release a new version of "mingw-zlib" for cygwin(*) now 
that zlib-1.2.1 has been released.  But I can't...

(*) this package is a msvcrt-linked version of zlib, used by cygwin 
internal projects (like setup.exe and others) which are not allowed, for 
whatever reason, to link against cygwin1.dll or the cygwin version of zlib.

So here's the error I get:

gcc -mno-cygwin -O2 -o example.exe example.o -L. -lz -L/usr/lib/mingw
/usr/lib/gcc-lib/i686-pc-mingw32/3.3.1/crtbegin.o(.text+0x5):crtstuff.c: 
undefined reference to `___w32_sharedptr_initialize'
collect2: ld returned 1 exit status
make: *** [example.exe] Error 1

I snooped around in the gcc CVSWEB and found this file in the cygming332 
branch:

gcc/gcc/config/i386/t-cygming
----------------------------------------------
LIB1ASMSRC = i386/cygwin.asm
LIB1ASMFUNCS = _chkstk

# cygwin always has a limits.h, but, depending upon how we are doing
# the build, it may not be installed yet.
LIMITS_H_TEST = true

# If we are building next to winsup, this will let us find the real
# limits.h when building libgcc2.  Otherwise, winsup must be installed
# first.
LIBGCC2_INCLUDES = -I$(srcdir)/../winsup/w32api/include

LIB2FUNCS_EXTRA = $(srcdir)/config/i386/w32-shared-ptr.c

winnt.o: $(srcdir)/config/i386/winnt.c $(RTL_H) $(TREE_H) $(CONFIG_H)
	$(CC) -c $(ALL_CFLAGS) $(ALL_CPPFLAGS) $(INCLUDES) 
$(srcdir)/config/i386/winnt.c

# Don't run fixproto
STMP_FIXPROTO=
STMP_FIXINC=stmp-fixinc
----------------------------------------------

Now it refers to a file "config/i386/w32-shared-ptr.c" which seems 
promising -- but doesn't appear to exist in CVS.  Is this a problem?
