Disabling warnings from within the source

[Andre Majorel]

Is there a way to disable a class of warnings from within the
source, through a pragma or some magical __keyword__ ? Bonus
points if it can be done for just part of a translation unit.

I'm looking for a notional equivalent of this :

/* some code */

#ifdef GCC
__nowarn_begin__ (no-char-subscripts)
#endif

/* some code that purposedly uses chars as subscripts */

#ifdef GCC
__nowarn_end__
#endif

/* some code */
