 * vlibc — public API.
 *
 * vlibc is Vox's modern replacement for glibc. This header is the public entry
 * point for vlibc's own extensions; the C and POSIX standard headers
 * (<stdio.h>, <string.h>, ...) are provided separately and are gated by the
 * active compatibility profile.
 *
 * Compatibility profiles (build-time; see configure.ac and docs/compatibility.md):
 *   1  onlyposix   pure POSIX, nothing more
 *   2  muslmimic   musl-like, light
 *   3  muslext     musl-extended
 *   4  spoof       glibc replica (drop-in compatibility)
 *   5  vlibc       glibc-extended, the default
