The main problem here is that the way fact tables are currently compiled
is Unix-specific and external commands run by the Mercury compiler using
libc's system function are executed by cmd.exe on Windows**.  It doesn't
understand Unix specific stuff.  An additional problem, may be that that
the compilation of fact tables requires the Unix sort, cut and cat
utilities and those may not be available in the cmd.exe environment.
(I'm not sure if the MinGW/MSYS versions will actually work outside of
the MSYS environment.)

I will take a look and see if there is some way we can avoid the
Unix-specific stuff on Windows.

I don't think the value of $TMP is the issue here.

(** strictly speaking they are executed by whatever the environment
variable COMSPEC is pointing to.)

I would guess that's coming from the C compiler.  Could you please
re-run that and inclucde the option --verbose-commands, so that we can
see what's going on.
