FYI, it's newlib that provides the incorrect declaration. It's one of 
those cases where newlib's declarations don't quite match POSIX/UNIX98, 
but small enough that nobody has bothered to fix those. Mostly has to 
do with signed vs unsigned (eg., size_t vs ssize_t) and those little
nits. Interestingly enough, someone, quite possibly Joel Scherrill, had 
gone through newlib and fixed most of these, if not all, but only for 
RTEMS! 

POSIX:
    ssize_t read (int, void *, size_t);

newlib:
    #ifdef __rtems__
      ssize_t read (int, void *, size_t);
    #else
      int read (int, void *, size_t);
    #endif

Perhaps Chris and/or DJ know why that is the case.

When you have a conflict between Glenn Fowler's AT&T AST and another 
library, chances are that AST is doing the right thing.

Mumit
