Eric,
	In my experience dll's from gnu32 can be loaded into 
other executables but not into other dll's. So, if Excel is
using a dll to load your dll, it will fail. I have found that
the 'minimalist' gnu32 (check cygnus web site), can produce 
dlls that are loadable by other dlls. 
	I will reiterate a previous plea, if anyone knows the
source of this behaviour, do tell. There is no compiler I know
of with the math library of gcc, what a pleasure it would
be able to write dlls with gnu32.
