  And I did not write it in perl to avoid people willing to
convert it to awk, telling awk is more portable/reliable :-)

  The attached patch works with gawk and mawk. I don't have
access to a BSD or Solaris Xorg build right now, but I believe
it should also work with posix awk. Can someone confirm please?

  It could also be a good idea toadd a small set of hardcoded
symbols in the template sdksyms.c, so that the linker would
link all symbols. The previous *sym.c files were very outdated,
but still, referenced enough symbols to prevent this problem...
