I'll try tonight at home and I'll let you know.
However the compiler does have the bug. I tried the source code provided
with the bug report and it doesn't work if -O2 is passed at compile time
but works OK without it. So once again is there an easy way to turn all
optimization off when compiling pwlib, openh323 and gnomemeeting? Or
should I just go and patch all the generated Makefiles?
Thanks
