You ask for details so here they are.
I don't use MacPorts or any other non-standard build environment, I
don't suffer compiler bugs so I don't need 'CCFLAGS="-O0" to correct
a buggy compiler and I have applied every patch and bug-fix released
and experience no build issues with any other software source.
Here's what I start with:
Using gcc-3.3 (it's old but it compiles for ppc)
cd /private/var/tmp/clamav/clamav-1.obj && CFLAGS="-arch ppc -g -Os -
pipe -pipe -no-cpp-precomp -arch ppc" CCFLAGS="-arch ppc -g -Os -pipe
" CXXFLAGS="-arch ppc -g -Os -pipe " LDFLAGS="-arch ppc "
TEXI2HTML="/usr/bin/texi2html -subdir ." rm -rf /tmp/clamav/Release
&& mkdir -p /tmp/clamav/Debug && ln -sf /CLAMAV_BUILD/Release /tmp/
clamav/Release && CFLAGS="-DFD_SETSIZE=2048" ./configure --prefix="/
usr" --mandir=/usr/share/man --sysconfdir=/etc --enable-bigstack --
with-user=clamav --with-group=clamav --with-dbdir=/var/clamav --
disable-clamav
make
make install # no issues with the build or install but nothing seems
to works and segfaults (expected behavior)
Using gcc-3.3
cd /private/var/tmp/clamav/clamav-1.obj && CFLAGS="-arch ppc -arch

CCFLAGS="-arch ppc -arch i386 -g -Os -pipe " CXXFLAGS="-arch ppc -

Thanks, I don't have a PPC here, but I am going to install fedora

Legacy systems are unfortunate. However, I think you would be hard
pressed to find any open source project today supporting that, so I
don't think it is that ridiculous to not expend the effort to actively
support it. I wouldn't be surprised if the code required to make it
compile on your system *and* modern systems caused performance
decreases
(or even not compile on modern gcc!).
There might be a small chance that you would need to maintain a
separate
patchset to maintain this compatibility since having it compile on
both
your legacy and modern systems would be detrimental to other ClamAV
users.
