Ok, for any executable that is not the compiler, e.g mslice.exe,
mercury_profile.exe, we get the following error:

error LNK2019: unresolved external symbol __wgetmainargs referenced in
function _mercury_win32_args

Is __wgetmainargs included in the static version of the library on
Windows, i.e. in libcmt.lib?  Or is only part of the dynamic library?
(MSDN is its unsual unhelpful self on this issue.)

I will try reconfuring with --with-msvcrt enabled and see if that helps.
In the meantime, This is all rather curious, because mercury_compile.exe
does build (and indeed runs).  Any idea what we might be doing
differently in the compiler directory?

Julien.
