[Octave-bug-tracker] [bug #54235] problems building Octave on Solaris

[Michele]

Follow-up Comment #151, bug #54235 (project octave):

Going after these errors in order, and having heard nothing back on the gnu
mailing list in three days, I looked at the offending code in auto-host.h.

It says "error: declaration does not declare anything"  


/* Define to `long' if <sys/resource.h> doesn't define. */
#ifndef USED_FOR_TARGET
#define rlim_t long
#endif


What's wrong with that declaration?

Turns out rlim_t isn't used anywhere else in this file so I just commented out
the whole #ifndef block and ran gmake again.  That did indeed take care of
this error, and a few others too.  Now I'm left with just two errors:
