I'd finger the project autogenerator as the main culprit. It treats Microsoft's custom environment as the golden standard. It's possible to write portable code in Visual C, but they don't make it easy for you!

__BUILTIN_CONSTANT_P(3) 				   BSD Library Functions Manual 				   __BUILTIN_CONSTANT_P(3)

__builtin_constant_p -- GNU extension to determine compile time constants SYNOPSIS
int __builtin_constant_p(value); DESCRIPTION
The __builtin_constant_p() is a GNU extension for determining whether a value is known to be constant at compile time. The function is closely related to the concept of ``constant folding'' used by modern optimizing compilers. If the value is known to be a compile-time constant, a value 1 is returned. If __builtin_constant_p() returns 0, the value is not a compile- time constant in the sense that gcc(1) was unable to determine whether the value is constant or not. EXAMPLES
A typical example of the use of __builtin_constant_p() involves a situation where it may be desirable to fold the computation if it involves a constant, but a function call is needed otherwise. For instance, bswap16(3) is defined in NetBSD as: #define bswap16(x) (__builtin_constant_p((x)) ? __byte_swap_u16_constant(x) : __BYTE_SWAP_U16_VARIABLE(x)) SEE ALSO
gcc(1), __builtin_object_size(3), __builtin_return_address(3) CAVEATS
This is a non-standard, compiler-specific extension. BSD
