Alexandre,
Glancing at the inline rule which was being used:
~ sed '/^#/ s|y\.tab\.c|$@|' y.tab.c >[EMAIL PROTECTED] && mv [EMAIL
PROTECTED] $@
Only the filename portion of the path is being replaced here. The
ylwrap script actually replaces an absolute path in the #line
directive with just the filename:
...
~ # Quote $INPUT_DIR so we can use it in a regexp.
~ # FIXME: really we should care about more than `.' and `\'.
~ input_rx=`echo "$input_dir" | sed 's,\\\\,\\\\\\\\,g;s,\\.,\\\\.,g'`
...
~ sed "/^#/{s,$input_rx,,;s,$from,$2,;s,$FROM,$TO,;}" "$from" >"$target"
...
It's the absolute path which some yacc compilers leave behind that we
need removed to avoid this problem. I'd be just as happy if it
happened in the inline version, but I thought it would be simpler to
just use ylwrap since it already exists and does what is needed. Even
if it does a little extra work at least the compatibility cruft would
only need to be maintained in a single location.
Cheers,
Derek
