[Scummvm-devel] Compilation on IRIX?

MIPSpro 7.4.4 is the last / least-buggy version of the MIPSpro compiler, 
and the only one able to compile ScummVM without workarounds, thus it's 
the only 'supported' version of MIPSpro.

GCC is generally available too, but (at least in the past) isn't able to 
optimize as well, which makes compilation with MIPSpro a must for the 
older, slower machines.

No, cxx_verc_fail is never set to "yes" (or anything else), as 
cxx_version contains "7.4.4".
Thus configure doesn't fail, since the check further down only checks if 
cxx_verc_fail is set to "yes".

No, the test should remain. You can, however, safely add a 
'cxx_verc_fail=no' to the irix host_os case if it helps clarity.
