was trying to build 2.3 under 6.5.21m.
The compile halted on posix.c at line 447. IRIX does not have the ltm->tm_zone field, but rather uses the tmzone and tmzone fields available for __CYGWIN__ macro for conditional macro.
again in uposix.c the same code pattern exists and the same fix should work.
I am sure that someone more familiar with the build can suggest a good way to incorporate this. I have not spent anytime in the configure etc so I kludged it just to get past the problem and see what else breaks.
still having lots of fun with setenv and unsetenv - anyoone shed any light?
