[mercury-users] rotd-2002-12-03 -- C interface problem

[Ondrej Bojar]

Hi.

I recently switched from rotd-2002-09-24 to rotd-2002-12-03 and there is
something new with the C interface.

First of all: mmc now generates .mh and .mih files for every module
(even if it doesn't export anything for C) and mmc has stopped generating
.h files for modules than *do* export some functions.

What are the .mh and .mih files and what should I fix to get .h files as
well? (So far I do #include .mh instead of .h and it worked in some
cases.)

And the second question is a bit foolish: My source code of a project is
rather untidy; I had to export my own predicates to construct mercury
lists from C++ (the default macros worked in C only, is that still true
with rotd-2002-12-03?). But now, the modules don't compile. Is this my
fault?

Thanks, Andrew.

Listing follows:
