Bogus "error: unterminated comment"

No, it's not that. The problem is that RFLCT.FOR has a uppercase .FOR
extension, which indicates to gfortran that C-style preprocessing is
required, while it is not performed for a file having lowercase .for
extension. C-style preprocessing, being C-style, doesn't deal well
with /* and */. Some compilers deal with it (intel, sun), some don't
(g95, gfortran).
