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.

PR fortran/28526
* gfortran.dg/keyword_symbol_1.f90: New test.
* gfortran.dg/spread_shape_1.f90: Add missing warning with
