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.
