These line numbers are off. There's no '&' anywhere here. Any chance this f=
ile=20
wasn't passed through yacc/lex? Does an '&' show up in raw cpp output (mayb=
e=20
memchr was defined as some macro)? Try:
cpp -DPERL_CORE -DHAS_FPSETMASK -DHAS_FLOATINGPOINT_H -fno-strict-aliasing =
=2Dpipe =A0\
-std=3Dc89 -O -Wall -ansi =A0 -W -Wextra -Wdeclaration-after-statement \
-Wendif-labels -Wc++-compat -o toke.out
Then inspect toke.out.

Problem with today's modular software: they start with the modules
and never get to the software part.
