/*
 * links — the text-mode web browser.
 *
 * Two modern-compiler fixes (verified):
 * - ftp.c: const-correct strchr (clang 16+) rejects assigning through
 *   the const result; sed casts the operand to char*.
 * - CFLAGS=-std=gnu17 keeps pre-C23 strchr semantics everywhere else.
 *
 * Optional deps (openssl/libevent/libjpeg/libpng/libtiff) disabled —
 * http-only until an openssl package exists.  Terminfo from store ncurses.
