Maaaan ... much as I love you - that's not an astute assertion to make.
ActivePerl already supports MinGW's gcc compiler. One can use either that compiler, or an MS compiler, with ActivePerl - and that state of affairs would not change if AS distributed MinGW's gcc with their ActivePerl builds.
If the corporate clients did not wish to use the gcc compiler that was being (hypothetically) shipped with ActivePerl, then they would simply ignore its presence and proceed with "business as normal".
