[DotGNU]Portable.NET update - C compiler

[Rhys Weatherley]

Hi all,

I'm currently working on improving the C compiler and the pnetC library so 
that we can hopefully get it to a useful state soon.

In the past few days I've fixed some bugs in the compiler, particularly the 
one where an error wasn't given for missing symbols.  So it should be easier 
to diagnose which things are missing now.  Many of the VerificationException 
errors that people have been seeing were due to unreported missing functions.

In pnetC, I've been working on signals, pthreads, group file routines (e.g. 
getgrnam), error reporting (strerror, perror, etc), and general thread-safety 
of library functions.

The stdio routines are still a bit of a mess, including printf and scanf.  
They are high on my TODO list, but there are still some dependencies that I 
need to sort out first.

If you would like to help out on the pnetC project, then please read the file 
"pnetC/doc/HACKING" in CVS, send me an e-mail, or drop into #dotgnu this week 
sometime.  pnetC is the biggest area that needs work, and should be pretty 
simple for anyone familar with C: porting and/or re-implementing common C 
functions.

Cheers,

Rhys.
