Hi..

back from snowboarding, so i may as well wade in on this thread again =)

if its any reassurance, glob is POSIX, AFIAK (and also according to the man 
pages on my system). armed with this self-assurance, i did some searching and 
here are system with glob documented in the section 3 of their man pages:

  - linux
  - *bsd
  - tru64
  - sunOS 5
  - solaris
  - AIX

and they all return a glob_t, as POSIX tells them to. i'm sure that other 
unices therefore also have it, at least any released in the last several 
years.

so ... it looks like you could do a glob() routine and have it portable 
across most if not all unixes.. note that this is without experimentation, 
theory only so i'm sure one of the Unix vendors managed to get it wrong in 
some small way.. on the whole however, i trust the man pages... perhaps i'm a 
fool =P
