/*
 * links — the text-mode web browser.
 *
 * HTTPS is a kappa feature (enable: packages { links { features { ssl =
 * true } } }): "--without-ssl" sits in the line always, and the feature
 * flag's "--with-ssl=<store>" comes AFTER it, so the last flag wins when
 * enabled.  When disabled, the explicit --without-ssl beats the host's
 * openssl headers.
 *
 * 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.
