I believe the real underlying cause is that /lib/w32api/libntdll.a
contains a atoi function header (I see that in
http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/winsup/w32api/lib/ntdll.def?cvsroot=src
together with a zillion other WinNT/2K/XP functions). This is wrong
because Win9x have only a very limited set of functions in ntdll.dll.
Yes, I thought it is a w32api bug at first too. Who is the maintainer
of w32api?
The MingW team. However, the symbols in ntdll.def are there already for
a long time and they are apparently ok even though it rolls up my toe nails.
Also, the fact that 9x has only a limited set of functions in this DLL
doesn't mean that the NT symbols shouldn't be present.
Explicit linking against ntdll is the problem here. I guess the right
thing would be to link against -lcygwin first.

Or not explicitly linking against ntdll. It will obviously be called in
if it is needed.

many of them are only used for specific extension modules.

Sorry, I was thinking of atof. Anyway, Win32CORE.c doesn't use it.

Or, if you prefer, indiscriminate linking to ntdll.dll in all Windows
versions is the actual culprit.
