I know at least two free compilers... lcc and mingw 
to me the greatest obstable is to maintain the build environments for
all the possible compilers (MSVC, Borland...)

this is utterly true for low level APIs (like kernel)
however, testing a highler level API will depend on all the others DLL
the tested DLL depends on... and here you may introduce some
