Good point, and thanks for noting it. I was only thinking of independent actively developed production compilers in my space of expertise, where C/C++ seems to be down to GNU, Clang, and EDG-based compilers, while Fortran still has at least GNU, Intel, nvfortran, LLVM Flang, NAG, and XLF. A decent C89 compiler for a single target is only about a 10K LOC project and there must be more than a few of them out there.
