in reply to h2xs problems (aka: h2xs ate my memory)
I just ran this on my machine, after installing the latest versions of C::Scan and Data::Flow, and here's what I got:
root@linux arf# time h2xs -x /usr/include/bfd.h
Scanning /usr/include/bfd.h for functions...
No time at all. 'h2sx' is version 1.19. This all running on a mixed version RedHat system, 1Ghz Athlon, 512MB.
