testing on POSIX systems:
  perl Makefile.PL -xs ; make distclean ; perl Makefile.PL -xs ;
    make && make test >xs.test.out 2>&1
  perl Makefile.PL -pureperl ; make distclean ; perl Makefile.PL -pureperl ;
    make && make test >pp.test.out 2>&1
  echo === XS make test output ===
  cat xs.test.out
  echo === PP make test output ===
  cat pp.test.out
  echo XS: `grep Result xs.test.out`
  echo PP: `grep Result pp.test.out`
  rm -f xs.test.out pp.test.out

## last tested version list, ? = not yet tested
## POSIX/UNIX-y OS's are tested both with and without cc
## most tested like so: perl Makefile.PL ; make distclean ; perl Makefile.PL && make && make test ; echo -n "w/ cc tests above (hit enter)..." ; read X ; make distclean ; sudo mv /usr/bin/cc /usr/bin/gcc ~/ ;  perl Makefile.PL && make && make test ; echo those were tests w/o cc ; sudo mv ~/cc ~/gcc /usr/bin/
