Hello world,
Steve found a test case where unsigned constants were not handled
in a module. Single-line patch committed as obvious and simple,
r15-5341-g66096151afc6631f8f2a3458b154c5daa822b963 .
Best regards
Thomas
Handle unsigned constants for module I/O.
gcc/fortran/ChangeLog:
* module.cc (mio_expr): Handle BT_UNSIGNED.
gcc/testsuite/ChangeLog:
* gfortran.dg/unsigned_42.f90: New test.
