The most important word in that sentence is "If".

Because that assumption is not valid at all.

VMS C and C++ has some VMS specific language extensions.

VMS Fortran and Cobol has a lot of VMS specific language extensions.

VMS Pascal and Basic are very different from those languages on
other platforms.

And both GCC and LLVM only have good support for C, C++ and Fortran
anyway.

And then there is Macro-32 and Bliss-32 ...
