First we check for C99 support in Makefile.detect, looking for the header we need and verifying whether it is the right one by using a definition required by C99 standard to be present in that header. uintN_t types are optional, but implementations are required to provide corresponding limit #defines for the types they support, so we can check for this with preprocessor only. Finally, we define SEXP_UINTN_DEFINED for any sexp_uintN_t we have so that the code can use #ifs to check for exact integer support. |
