Agree with that - I didn't realise this would put yylex on top of
the list if byte manipulations were the real problem; my language of
choice predates automatic lexers by two decades, and I didn't
really kept up with the field after the card readers were scrapped
around here :-)

Well, I don't mean to argue this to death, but in _my_ copy of gcc,
the first two fields in the RTX structure are 16 and 8 bits wide,
followed by 7 one bit flags.

Sure, but I hoped to pinpoint a *common* cause for the difference
between gcc on the Alpha and on the i386, given that Jim's
experiment shows that no *single* routine is responsible.
