re PR fortran/28526 ('end' is recognized as a variable incorrectly)
2006-09-18 Paul Thomas <pault@gcc.gnu.org> PR fortran/28526 * primary.c (match_variable): If the compiler is in a module specification block, an interface block or a contains section, reset host_flag to force the changed symbols mechanism. PR fortran/29101 * trans-stmt.c (gfc_trans_character_select): Add the post block for the expression to the main block, after the call to select_string and the last label. 2006-09-18 Paul Thomas <pault@gcc.gnu.org> PR fortran/28526 * gfortran.dg/keyword_symbol_1.f90: New test. * gfortran.dg/spread_shape_1.f90: Add missing warning with pedantic compilation option.
