+[PATCH] fix build with --disable-crypto
+
+options.c is missing the definition for struct context when built with
+--disable-crypto, as it then doesn't get pulled in through push.h,
+leading to build errors like:
+
+options.c: In function ‘parse_http_proxy_fallback’:
+options.c:1474: error: dereferencing pointer to incomplete type
+options.c:1477: error: dereferencing pointer to incomplete type
+options.c:1478: error: dereferencing pointer to incomplete type
+
+Fix it by including forward.h
