Last Friday, I posted an article titled "Versions", asking about
versions of gcc for an HP PA-RISC 9000/715 workstation running HP-UX
9.01.  I received some help from inside CONVEX and help from outside,
especially from jbuck@ohm.EECS.Berkeley.EDU (Joe Buck) and
law@snake.cs.utah.edu (Jeff Law).

Jeff Law wrote that 2.4.5, the latest version, is reasonably stable.

-g and gdb do seem to work, modulo the caveats in README (it doesn't
work well with shared libraries).

The HP system library doesn't support long long.  The thing I noticed is
that *printf's %lld and %llu aren't supported (they are interpreted as
%ld and %lu respectively).  I asked Jeff Law whether they've ever used
glibc, and he replied

I wrote a manual lltoa conversion function in the obvious,
quick-and-dirty fashion.

- strip sign
- modulo 1000000000 and divides by the same to split the number into
  three chunks
- sprintf %02lu%09lu%09lu
- strip leading zeros (except the rightmost if the number's zero)
- prepend a sign if needed
