Hi Bob,

In case you missed it in one of my previous notes to Phillip, I did
finally make a functional dll following these steps:

1. Ran my configure command with all my usual options in pcre-7.0.

2. Ran same configure command in pcre-7.1-RC3

3. copied makefile and makefile.in from pcre-7.0 to pcre-7.1-RC3

4. edited both of the above to change ucptable.c to ucptable.h

5. ran make in pcre-7.1-RC3. There were numerous warnings about various
things that were already defined. But nothing fatal happened before the
dll was produced. In fact, I think I got all the shared and static
libraries (despite having asked only for shared, and no cpp.)

I'm going to put together a zip with a coff file you can try as well.

Regards,
Sheri
