    • Add test coverage for _Pragma (PR preprocessor 69126, 69543, 69558) · 1d3121af 
      We had some regressions in the ability for _Pragma to disable a warning
(PR preprocessor/69126, PR preprocessor/69543, PR preprocessor/69558).

This patch attempts to add more test coverage for this, for the
various combinations of:
  - various warnings:
    -Wunused-variable
    -Wuninitialized
    -Wdeprecated-declarations
  - various combinations of location of _Pragma relative to location of
    the warning:
     - _Pragma is in a macro, warning isn't a macro
     - neither is in a macro
     - _Pragma isnt't in a macro, warning is in a macro
     - in different macros
     - both in the same macro
  - C vs C++ frontend.

It adds some XFAILs:
  - pr69543-1.c for C++ (fixed in the followup patch)
  - pr69543-3.c for both C and C++
  - pr69543-4.c for both C and C++
  - pr69558.c for C++ (moving it from gcc.dg to c-c++-common,
    marking it as xfail for C++ for now)

level that also checks for unused static const variables in included
