Seems the failure has changed with the latest FFmpeg. It was quite a 
while ago that I tested with 3.4.6 so perhaps the problem was already fixed.
Since the last time I ran the regression tests the number of errors has 
increased from one to three and seem slightly different. 3.4.6 and 3.3.5 
both fail the same.
Previously with 4.3.2 FFmpeg was trapping in libc. when doing the dv-50 
test IIRC. Now crashing in the svq1 test in FFmpeg_g. This could be 
related to the optimization level. Unluckily FFmpeg doesn't compile with 
--disable-optimization. (can't find a register)

gcc432.dll dependency

Hi/2.

Paul, all the programs built by the latest GCC v4.3.2 have a dependency
on gcc432.dll. Will this dependency be removed later or not ?

If possible, I would like to release some libs and programs without
dependency on gcc432.dll.

And, do you have a plan to port the latest 'as' ? At least, 2.16.92. It
is needed to support SSSE3 instruction.

Thanks.

Maybe... There are some issues with c++ exceptions when the static gcc  
is used - gcc 3.3.5 gets around this by included the exception  
handling stuff in libcXX.dll.  As Dave mentioned, using -lgcc should  
force the use of the static library

Yes - this is planned.  We're currently at binutils 2.16.1 - the  
intent is to get us to the latest level (2.19 IIRC) - but there is no  
timeframe for this, other than it will be after the mozilla issues  
with 4.3.2 are resolved (hopefully this won't be too far away).

Cheers,

Paul.

Thanks, but I would like not to specify additional flags if possible.

If you would follow the gcc 3.3.5 way later, I would wait until then.

Good. And it's not urgent. I wish the mozilla issues to be resolved soon.

Thanks for your efforts,  all the time.

Updated GCC 4.3.2 build

Hi All,

Not yet available on my webpage, but I'm announcing it here and on the
mozilla os/2 group first in the hope of some feedback prior to the 
'public' release.

Binaries: http://download.smedley.info/gcc-4.3.2-os2-20090116.zip
Patches against official source: 
http://download.smedley.info/gcc-4.3.2-os2-20090116-patch.zip

Changes since last release:
- Revamped emx.c and emx.h based on the changes to winnt.c & cygming.h
that were made between GCC 4.2.x and 4.3.x (20090116 build)
- Fixed compilation of Seamonkey (and presumably Thunderbird) 
(20090116 build)

Sorry it's taken so long to fix the dllimport/dllexport problems with 
Seamonkey - I wasted a serious amount of time trying to update the 
code in emx.c/emx.h to work with GCC 4.3.x - in the end I revamped it 
based on the latest win32 code which I should have done much sooner.

http://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution
=FIXED&target_milestone=4.3.3

No OS/2 specific fixes have been made since the Jan 16th build of GCC 
4.3.2.

Hi Paul,

thanks for your work!
Testing ggc results in
"gcc: error trying to exec 'as': execvp: No such file or directory."
As i found out, as.exe is linked against gcc432.dll instead of 
gcc433.dll. After copying the dll to lib-path everything works fine.

Best regards
Michael
