nonstandard extension used : 'keyword' keyword reserved for future use
At present, the keywords that are disabled as reserved in the sense of triggering this warning are:
__nounwind, __resume and (unless -Binl is active) __thiscall
This warning is promoted to an error automatically (as if the corresponding -we option were generated internally before the compiler acts on options from the command line). By default however, this is a level 1 warning and a
#pragma warning (default : 4234)
restores it to level 1 (no matter that the product documentation assigns this warning to level 4).
