Mcs is not an "old compiler". It is the compiler of the .NET 1.1
profile. Since this profile is not installed on your machine,
mcs is likewise not available because it would be of no use
w/out the core 1.1 assemblies.

This is a bad idea, IMO. .NET is very explicit at compile
time, i.e. you must explicitly specify the runtime version
you're compiling for and the assemblies you're binding
The runtime version is implicitly set by the specified compiler:
mcs -> .NET 1.1
gmcs -> .NET 2.0
dmcs -> .NET 4.0
behind your back.
Having a hypothetical "mcs" pointing to a "current" compiler will
not solve the problem of having to choose a runtime version
at compile time. This is fundamental in the .NET world, even
if people don't always recognize this feature.
There are efforts to make "mcs" a multi-target compiler (probably
under a new name and with script wrappers for "mcs", "gmcs",
"smcs", "dmcs"), but even then you'll have to specify the target
runtime version via a command like switch (or resort to the
