hmake-3.08 and RedHat 7.2

[Ravi Nanavati]

I've continued to poke at the issue and it turns out that I had deeper 
problems with my ghc-6.2.1 install. Whatever Haskell programs I built 
(including hmake) had a broken ghc RTS - even <program> +RTS -help -RTS 
wouldn't work, to say nothing of programs that tried to set RTS hooks.

I also tried installing ghc-6.2 and had the same issues. Finally, I 
decided to rebuilding ghc-6.2.1 from source, and this solved everything:

- hmake 3.08 built cleanly from source (System.system worked)
- compiled Haskell programs started processing their RTS flags again
- my program that set an RTS hook doesn't crash on startup anymore

Given that, I think there isn't a bug in ghc per se, but rather a 
problem with the recent prebuilt glibc-2.2 ghc builds. I'm not sure what 
that might be, but I hope I've provided enough details to help isolate 
the issue (and please let me know if there are any additional details 
that would help).

Thanks,
