2998d3fde7 Fixed a comma error. 
Added the --disable-threads option to GCC configure (to avoid pthread errors
when building code with LLVM).

This makes LLVM and the generated C code more portable.

01b2d61311 Fixed the CBE on Solaris/Sparc. We need to define the return value of 
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

5be28c59c6 Removed the pthread_once() function because it doesn't actually do 
what it's supposed to do.
Just leave this library as a dummy library for now until we have time to
port a real pthread library (or get glibc working).
