gcc disable ALL warnings for a few lines of code

Question

I have the same problem as described by Jonathon Reinhart here: Temporarily disable gcc warning on redefinition

That is because I have to use thrid party libraries (C only) which throws tons of warnings like this

Warning "__always_inline" redefined [enabled by default]

What I want is something like this:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-W???"
  #include "someheader.h"
  #include "otherheader.h"
#pragma GCC diagnostic pop

Is there a way to disable warnings by gcc which are enabled by default with a

#pragma GCC diagnostic ignored

EDIT: here is the block causing the warning (file: compiler.h):

#if defined(__CC_ARM)
#   define __always_inline   __forceinline
#elif (defined __GNUC__)
#   define __always_inline   inline __attribute__((__always_inline__))
#elif (defined __ICCARM__)
#   define __always_inline   _Pragma("inline=forced")
#endif

it's rude of them to use reserved names like that. Have you contacted the vendors of the libraries? You oould ask them to supply header files suitable for use with a C compiler. or you could attack the supplied headers with sed or similar and change the macros to not use reserved names. — Jasen

"sweep the bugs under the rug" seems like a sub-optimal solution to this problem — Jasen

The vendor (Atmel) is informed: asf.atmel.com/bugzilla/show_bug.cgi?id=3486 You're right. Sweeping bugs isn't the best solution, but fixing bugs like redefinition of exact the same __always_inline lines for every new version of the library again and again is even worse. — Johann Horvat

I fixed it by undefining all lines where __always_inline was defined. :-( Thanks Jasen for helping!
