It's somewhat more complicated unfortunately. There are numerous gnu extensions which are used by people using gcc. I don't know if the HP- UX compiler is c99 or not, but that may be a second issue, especially for FLINT.
On top of the compiler issues, if you port to the HP-UX OS you then have a whole different unix that your build system has to handle. If you've been watching the Solaris port you might get some idea of what the issues are there. When I talk about FLINT supporting HP-UX I am mainly talking about the compiler. I also understand from experts that it is a particularly fussy and bug-ridden product. That may be completely wrong. I am merely reporting hearsay. But I don't particularly care to find out. Bill.
