The APDA CDs did have a shell like that, I once used it to port
my 3D conversion software.   I had to find a way to make 'makefiles'
that would compile the code on several platforms: Amiga, 32-bit DOS,
Windows, SGI and Linux.  And I did.  It was also tricky to write
a filepath parser that could handle paths of any type and be able
to re-write them with the destination path's type, on a platform
that used neither type.  So my software could read an SGI model
on an Amiga and write out PC-style filename paths, for example.

But I think I first saw the colon separators in Mac Pascal code for 
DECnet.  I once helped port Thursby's TSSnet from Mac to Amiga.
