Unlikely. Windows DLLs are quite different from Unix shared libraries.
In particular, Windows binaries (executables and DLLs) import specific
symbols from specific DLLs; OTOH, Unix binaries don't care where an
imported symbol comes from, so long as it actually gets provided.
AFAICT, the circular dig2/vect dependency must be recent; it doesn't
occur in the last version which I built. There were some circular
dependency issues with the DBMI code, but ISTR that Radim said that he
had fixed that.

Is this related to cross-compilation?
