squid on sgi irix

Is there an issue with compiling and running squid 1.1.21 on an sgi
challenge m with 128meg ram and 9gig disk, running irix 6.2 and compiled
using version 7.2 sgi compiler and gcc version 2.7.2.3

Every time I compile, I get the following error messages appear on my
console even though under irix 5.3 and version 1.1.17 of squid it compiled
and worked brilliantly:-

ld: WARNING 84: /usr/lib/libcrypt.so is not used for resolving any
symbol.
ld: WARNING 84: /usr/lib/lib44bsd.a is not used for resolving any
symbol.
ld: WARNING 84: /usr/gnu/lib/gcc-lib/mips-sgi-irix5.3/2.7.2.2/libgcc.a
is not used for resolving any symbol.
ld: WARNING 85: definition of _calloc in /usr/lib/libmalloc.so preempts

ld: WARNING 84: /usr/gnu/lib/gcc-lib/mips-sgi-irix5.3/2.7.2.2/libgcc.a
is not used for resolving any symbol.

This goes on for several pages and does actually comile and give me an
executable file. But I have not had this working for more than two days
without falling over and totally locking up the sgi.

Can anyone shed any light on this problem or do I have to downgrade my box
to the seemingly more stable irix 5.3. Any suggestions would be most
gratefully received.

Thanks
