Re: todaycmn.h definitions.

Looks very good.

Can I put your example program in SVN too ?

Re: todaycmn.h definitions.

I've committed the patch.

Thanks for all your work !

Looks like Pedro has something better than I do. I'll keep my hands off.

[mingw32ce] New math support committed.

Hi all,

I just committed the new mingw/mingwex/mathce dir, which contains the 
c99 math extensions
to coredll.  This code is mostly based on the libm from OpenBSD, which 
is mostly based
on code copyrighted to Sun with the following license:

/*
 * ====================================================
 * Copyright (C) 1993 by Sun Microsystems, Inc. All rights reserved.
 *
 * Developed at SunPro, a Sun Microsystems, Inc. business.
 * Permission to use, copy, modify, and distribute this
 * software is freely granted, provided that this notice
 * is preserved.
 * ====================================================
 */

A few files are BSD (The Regents version) licensed.

---

I ported and ran the newlib/libm/test testsuite to mingw32ce, MinGW and 
Cygwin. 
The failures I get on mingw32ce are very similar to the ones I get on 
desktop MinGW,
which suggests that there isn't much we can do without overriding the 
native math functions
from coredll.dll.  Surprisingly on Cygwin (which is newlib based) I get 

[mingw32ce] A few ctype out-of-line functions added.

Hi guys,

The committed patch with the change log entry below was needed to build 
the newlib math testsuite
on mingw32ce.  The problem was that there is code on the testsuite that 
loads the
address of those ctype functions into a function pointer.  Since we only 
had inline versions
( __attribute__ ((__always_inline__)) ), I was getting link errors.  
These files implement
exactly what is found on the inline functions.  I've also updated the 
comment next to
the __CRT_INLINE definition on _mingw.h explaining it.

Cheers,
Pedro Alves

Another user (Daniel, CCed) has reported me privately that he built 
FFMpeg with cegcc, and that loading it from an MSVC app wasn't
working.  My guess is that the cegcc.dll isn't being correctly 
initialized.  There was a thread about that a few months ago, about someone
loading a cegcc based dll into a MSVC app, and that resolved into a 
patch being integrated into cegcc.  I can't find that
thread in my archives, but the symptoms were very close.  Anyway, with 
current mingw32ce from trunk and with the attached
patch I could build ffmpeg with the following options.

../ffmpeg-checkout-2007-01-21/configure \
    --enable-mingwce \
    --cross-compile \
    --cross-prefix=arm-wince-mingw32ce- \
    --arch=arm \
    --target-os=WinCE \
    --disable-static \
    --enable-shared

Both?   Looks like _GLIBCXX_USE_WCHAR_T isn't being defined.  Somewhat 
funny on a
supposedly fully Unicode OS.  :)
The problem should be in some configure test or in some header missing 
something.  Maybe look
in gcc/libstdc++-v3/ autoconf stuff if you are in the mood.

Found it.  wchar_t support is only enabled if some tests for c99 support in wchar.h pass.
The checks are found in gcc/libstdc++-v3/acinclude.m4.
(grep for "Check for template specializations for the 'wchar_t' type.", and then for
  "ac_c99_wchar")
