We are currently thinking about various remedies for this.  In the mean time
start with M-x first-error.

Ok, I thought that was only used interactively.  I will make it optional
again.

No way!  It states that only informationals are skipped.

It is only slightly incompatible.  Mostly tacking an '^' to the beginning of
your regexps should be enough.  I you used some of the wilder features, which
you can't figure out from the doc, ask me something precise.

If you call a function called *-internal, you're bargaining for trouble :-)
But the first arguments are emulated, except for the latter ones which had
been added recently.  What is it that you need?

Gladly, but I can only look at the sources I get.  This was published on news
several times with according warnings, but nobody came forth.  So we had no
choice but to install this, and make people call for help when they trip over
something — sorry!

That may be worth looking into!
