I've just tried it with DotGNU and compiled most of the library with both
mmake and mmc --make.  It looks like there is a bug in the MLDS backend that
causes it to duplicate definitions in the IL code when compiling
library/injection.m (which is where it dies for me at the moment)

Essentially the former, probably some of the XXX comments in
scripts/Mmake.vars.in also need to be addressed.  The patch below partially
adds support for DotGNU.

The only MC++ code I can see in benchmarking.m is commented out anyway; if at
all possible it should just be implemented in C#.

There shouldn't be any difference with 0.12.2.

Great! Looking forward to them.

Julien.
