Update re2c to most recent version.
I'll take it.
Doesn't build on 4.x:
source='code.cc' object='code.o' libtool=no DEPDIR=.deps depmode=gcc /bin/sh ./depcomp c++ -DHAVE_CONFIG_H -I. -I. -I. -O -pipe -march=pentiumpro -c -o code.o code.cc
code.cc:996: `char_type' was not declared in this scope
code.cc:997: confused by earlier errors, bailing out
*** Error code 1
This version seems to require GCC 3.4. However, that does not seem to
compile with 4.x.
to the Makefile. Can you verify this?
