I see, thanks. How are the built-in macros determined that clang defines
? Can I disable them with something similar to -nostdinc ?
The current Synopsis logic allows users to specify a compiler to emulate.
If this is a GCC variant, I query the compiler itself for macros and
headers (via `g++ -E -v -dD ...`)
If it is a MSVC compiler, I use hardcoded sets of flags.
This logic requires that the parser then doesn't add its own set of
macros, as those may actually conflict with what I feed in from the above.
