Description Daniel Holbert [:dholbert] (PTO Oct 21-25) 2012-01-26 13:18:06 PST
Filing bug on this warning:
HttpChannelParent.cpp:336:0: warning: ignoring #pragma warning  [-Wunknown-pragmas]

for this MSVC-specific line:
> 336 #pragma warning(disable : 4068)

The correct way to do this is demonstrated e.g. here in jsopcode.h:
> 286 #ifdef _MSC_VER
> 287 #pragma warning(push)
> 288 #pragma warning(disable:4100)
> 289 #endif
[...code that needs the warning disabled...]
> 436 #ifdef _MSC_VER
> 437 #pragma warning(pop)
> 438 #endif

That way, non-MSVC compilers don't see the pragma and won't complain about it.
