It occurred to me that I use the /MT option to compile the MSVCRTnn dll
statically. I tried removing that option. No change. But then I realised 
I had defined CCFLAGS for another option as well. Removed that. And
that turned the tables. To the worse, since linking now failed with 
tons of errors referring to the C Run-time library.

No. And it does not occur with ActivePerl 64-bit.

So far, yes.

I've yet to test that. But if the problem is the mix of MSVCRT versions,
this should not help.

Tried tonight to build on a pure 32-bit machine. No change.

Seems like Jan turns up whenever I ask a Perl question - unless I ask
it in ActiveStates own forums. This time he is silent, but vacation 
is commonplace this time of year.
