I finally got to the bottom of some unexpected behavior from the
amreb-linux target of the 4.1.2 compiler.
I'm hoping that someone can say if is this an optimization bug
(optimizes away too much) or a problem with this code.
extern int ReadChar( char *p);
/* grab a character from input

It is not OK to optimize away the post-increment. This is a gcc
optimization bug.
