gcc/testsuite/ChangeLog:
        PR preprocessor/69126
        * c-c++-common/pr69126.c: New test case.

libcpp/ChangeLog:
        PR preprocessor/69126
        * directives.c (destringize_and_run): Add expansion_loc param; use
        it when handling unexpanded pragmas to fixup the locations of the
        synthesized tokens.
        (_cpp_do__Pragma): Add expansion_loc param and use it when calling
        destringize_and_run.
        * internal.h (_cpp_do__Pragma): Add expansion_loc param.
        * macro.c (builtin_macro): Pass expansion location of _Pragma to
        _cpp_do__Pragma.
