Why do people have to be so stupid and immediately implicate the  
build tools or environment?

Because updates and bug-fixes were applied, your assuming that these  
are not done correctly or in compliance with the OS and build  
environment or that they are faulty.

First, you need to stop this bull-crap about non-standard and heavily  
modified and listen to the details regarding the issue you are told  
and stop focusing on the build tools which you have no clue about.

It is best that you accept my word that it is standard and in  
compliance with the OS, build environment and ADE.

I have confirmed the issue still exists under gcc-4.4 so it's not a  
build tool issue.

I now have generated a fully working  ClamAV 0.98.1 under gcc-3.3,  
gcc-4.0.0 and gcc 4.0.1 by cleanly autoreconf-ing the source tree.

Here's my configure for the working builds under the mentioned  
compilers:
CFLAGS="-arch ppc -arch i386 -g -Os -pipe -DFD_SETSIZE=2048 -arch ppc  
-arch i386" CCFLAGS="-arch ppc -arch i386 -g -Os -pipe " CXXFLAGS="- 
arch ppc -arch i386 -g -Os -pipe " LDFLAGS="-arch ppc -arch i386    
"   ./configure --prefix="/usr" --mandir=/usr/share/man --sysconfdir=/ 
etc --enable-bigstack --with-user=clamav --with-group=clamav --with- 
dbdir=/var/clamav --disable-clamav



Is using ltmain.sh from Debian-Ubuntu called portability amongst  
different environments??
