[tree-ssa][irix] libmudflap won't build - lots of warnings

["Billinghurst, David (CRTS)" <David dot Billinghurst at riotinto dot com>]

I have just built tree-ssa branch on irix6.5   libmudflap won't build, and there are a lot of compilation warnings.
I am happy to work through some of the issues if there is any interest.

The final error is

The first few warnings are due to missing headers
