In the process of fixed Pd-extended 0.43.1, I just found that on
Ubuntu/Maverick, Gem says this once I start Pd-extended:

/usr/lib/pd-extended/extra/Gem/Gem.pd_linux:
/usr/lib/pd-extended/extra/Gem/Gem.pd_linux: undefined symbol:
__sync_fetch_and_add_4
Gem: can't load library


according to the internet, this is a problem of the "-march=i386" flag
you are passing as CXXFLAGS.


What if I switched the OPT_FLAGS from:
        OPT_CFLAGS += -mtune=i686 -march=i386
to:
        OPT_CFLAGS += -march=pentium3 -msse -mfpmath=sse

The Pentium 3 came out in 1999, so that's quite old. For supporting older computers, people could use the official Debian/Ubuntu packages.
