Hi Bruno, the comments just above include the commands I ran to create
the resulting regular expression:
perl -lne '/^(?:extern )?(?:void|char) \*?(\w+) *\(/ and print $1'
lib/xalloc.h \
| sort | perl -MRegexp::Assemble -le \
'print Regexp::Assemble->new(file => "/dev/stdin")->as_string'|sed
's/\?://g'
However, I expect that it will be better to skip the regexp
optimization (that perl module is not always installed) and just use a
simple '|'d list of tokens, because that can all be done at test time
using portable tools.
