Re: multiple definitions linker error when building 2.0.5

The -frepo flag is best used when building executables
rather than libraries. What it does is defer
instantiating some template functions and just records
the fact that it needs them in a .rpo file (one per
cpp file). Then at link time, it consults the .rpo
files to instantiate all of the missing functions just
once.

If you're building a library then you're liable to
have a few functions missing unless you also perform
an explicit "closure" step on its contents:

gcc $(CFLAGS) $(LDFLAGS) -o junk <all .o files in
library>

Needless to say that this is a pain and absolutely
specific to GCC. So no, I didn't try building PWLIB or
OpenH323 like this.
