h2xs -x

[Yitzchak Scott-Thoennes]

On Ubuntu 12.04, I was able to follow exactly the example here:

http://perldoc.perl.org/perlxstut.html#EXAMPLE-4

except for adding -x to the h2xs invocation and not adding the foo stub to
the .xs file manually, and all worked just fine.

I'm a little confused that you say modern linux/gcc but appear to have perl
5.8.8.
