Avoid macro expansion

[soumyaranjansabat]

How can only the #if and #else be evaluated and pre-processed and avoid macro expansion of any available macros in the code?

Tried overiridng with few PreprocessorHooks but unsuccessful. Would really appreciate some help.

Input
#define PARAM_A STD_ON
#define LOOPVAL 3

#if (PARAM_A== STD_ON)
while(iter < LOOPVAL )
{

}
#endif

Expected Output
while(iter < LOOPVAL )
{

}

Not Expected Output
while(iter < 3)
{

}

Similarly for other macro like functions etc.

Supply me your PreprocessorHooks implementation and I'll take a look.
