Split-off from PR31310. g77 has a huge number (~20) of case options, cf. http://gcc.gnu.org/onlinedocs/gcc-3.4.6/g77/Fortran-Dialect-Options.html#index-g_t_002dfintrin_002dcase_002dinitcap-option-237 -fcase-preserve would probably be the most useful option; I don't know how much needed this option is for old code (cf.

This bug is old, many people have now transitioned their code from g77 times, and BIND(C) offers a standard-conforming way to achieve this goal nowadays. I fixed the doc, and think it's safe to close this PR as WONTFIX.
