I've been having fatal errors bootstrapping under Irix 6.3 using the 7.2 
compiler and CC='cc -n32' for the configure.  Looks something like this:

Configuring for a mips-sgi-irix6.3 host.
Created "Makefile" in /usr/local/src/building/here using "mh-frag"
21331:./conftest: rld: Error: unresolvable symbol in 
/usr/lib32/libiflPNG.so: __vtbl__9type_info
21331:./conftest: rld: Error: unresolvable symbol in 
/usr/lib32/libiflPNG.so: __T_9__nothrow
21331:./conftest: rld: Error: unresolvable symbol in /usr/lib32/libifl.so: 
__pure_virtual_called
[similar errors snipped]
21331:./conftest: rld: Fatal Error: this executable has unresolvable 
symbols
Links are now set up to build a native compiler for mips-sgi-irix6.3

I tried the bootstrap anyhow, out of curiosity.  The build seemed to work, 
but another executable failed during the make-install, when the .info files 
were being created (blech).  I scrapped that build.


I am trying a bootstrap now using cc -32.
