I get an error compiling octave-2.1.30/liboctave/oct-time.cc on
mips-sgi-irix6.5 with gcc-2.95.2

The error is:

This was raised as
http://www.che.wisc.edu/octave/mailing-lists/bug-octave/2000/96

timeval is:
  * conditionally declared in  /usr/include/sys/time.h (see below), and 
  * declared in /usr/include/sys/resource.h

To work around I have complied oct-time.cc by hand with -D_BSD_TYPES
There will be a better solution.  I'll look into it.


############## extract from /usr/include/sys/time.h #######################

#if _XOPEN4UX || defined(_BSD_TYPES) || defined(_BSD_COMPAT)
/*
 * Structure returned by gettimeofday(2) system call,
 * and used in other calls.
 * Note this is also defined in sys/resource.h
 */
#ifndef _TIMEVAL_T
#define _TIMEVAL_T
struct timeval {
#if _MIPS_SZLONG == 64
        __int32_t :32;
#endif
        time_t  tv_sec;         /* seconds */
        long    tv_usec;        /* and microseconds */
};
