I have never encountered this problem -- on my cygwin installation these
commands work just fine.

It would be useful if you could you explain what you found hard.

Cygwin is not required for compilation -- Mercury is capable of using
Visual C++ to compile the C the it outputs. 

Cygwin is mostly required for mmake.  Targetting .NET will not reduce
our dependency on Cygwin, because mmake is a shell script, not a Mercury
program.

Simon Taylor is currently working on moving the functionality of mmake
into the compiler.  This will reduce our dependency on cygwin a lot.

(We do already target .NET but not quite well enough for the compiler
itself to run in .NET).
