This causes some more modern constructs not to work and it also is the reason behind your problem. (cf. PR 28662). We need to use -traditional-cpp since "some tokens in C are not tokens in Fortran so you could get the wrong result." (A.P. in the other PR) The solution is to modify cpp to know fortran tokens (when called with -lang-fortran). Note this problem is not limited to gfortran; e.g. the NAG f95 compiler uses Sun's public-domain fpp (netlib.org/fortran/), which has similar problems. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29671 ^ permalink raw reply [flat|nested] 4+ messages in thread
