Thanks for the quick reply, Igor.  You're right: it doesn't seem like
a cygwin problem at all; more like a problem talking to Sun's jvm.dll
(which was presumably built with MSVC), but (a) I'm using the Cygwin
toolkit to built it, and (b) I figured I'd get better advice on the
Cygwin lists because of the expertise talking to Microsoft- and
related objects "from outside."

 From Sun's Java SDK (http://java.sun.com/j2se/1.4.1/download.html).
$ which jvm.dll java.dll
/cygdrive/c/j2sdk1.4.1_06/jre/bin/client/jvm.dll
/cygdrive/c/j2sdk1.4.1_06/jre/bin/java.dll

I just copied it straight from inonit.com (and it worked on NT 4.0 and
XP Home).  And JNI_CreateJavaVM takes three pointers as arguments
(which is what the patterns denote, right?), so 12 bytes seems right.

Shouldn't it know where the defaults are?  And if they're necessary
then it shouldn't work on NT or XP-Home either.
