Thanks Andrew for your response
I would try and get back to you
Yes the code has below block
#ifdef __cplusplus
extern "C" {
#endif
#ifdef __cplusplus
}
#endif
The source is C code with .C extension am adding /TP to MSFT:_*_*_CC_FLAGS
to overcome the variable declarations anywhere in the function
the same /TP does not throw any error with EDK I inf format of
[nmake.common]
C_STD_PROJ_FLAGS =
