Another possible way of rewriting this pattern is something like this:
(?:a(b)|).*d\1?
That is not true if 'a' and 'd' are expressions that may be equal. But
rewriting is not my concern.
You are right: concern is about compatibility.
there *are* differences between PCRE and Perl - thatis why the
"pcrecompat" man page exists. There will never be completecompatibility,
and anybody converting complicated Perl patterns to PCRE
should expect the occasional difference.
I was consider that any incompatibility with Perl must have weighty reason.
In this situation I don't see it.
Sorry, but that's the way it is.
It is a fact that I'm forced to take into account.
Thanx a lot anyway.
