From 71d2d37005479cbc86cf8cb97ab1aa84c2cbb89a Mon Sep 17 00:00:00 2001 From: Marcel Raad Date: Sat, 22 Apr 2017 23:12:07 +0200 Subject: [PATCH] curl-compilers.m4: accept -Og and -Ofast GCC flags -Og, introduced in GCC 4.8, optimizes for debugging experience. -Ofast, introduced in GCC 4.7, builds on -O3 and enables further optimizations breaking strict standards compliance. When specified in CFLAGS, these were always overridden by -O0 or -O2. Fix this by adding them to flags_opt_all.
