Fortran: fix for CHARACTER(len=*) dummies with bind(C) [PR115390]
gcc/fortran/ChangeLog: PR fortran/115390 * trans-decl.cc (gfc_conv_cfi_to_gfc): Move derivation of type sizes for character via gfc_trans_vla_type_sizes to after character length has been set. gcc/testsuite/ChangeLog: PR fortran/115390 * gfortran.dg/bind_c_char_11.f90: New test.
