Thanks for the suggestion. It makes some difference, but unfortunately
not to the output! 

With this change, I no longer need to compile with the -mrtd option,
and I need to change my dll.def file - using -mrtd I need

RHS
RHS AT 16=RHS

Using the explicit stdcall attribute in the .C file, and compiling
without -mrtd, the DEF file needs to be the other way round:

RHS AT 16
RHS=RHS AT 16

However, the program output is the same:

C:\PROJECTS\excel>exe
i 10.000000, j 11.000000, k -1.#IND00

Again, if I use exactly the same files, but replacing every "double"
with a "short", (and RHS AT 4 instead of RHS AT 16 where appropriate) the
program runs perfectly.

I just tried again, this time removing all stdcall references. The
program still fails, but this time I get

C:\PROJECTS\excel>exe
i 10.000000, j 11.000000, k 0.000000

(the last number is supposed to be the sum of the other two)

I'm still confused...
