Subject: ao-tools: Add lots of compiler warning flags to ao-tools build
X-Git-Tag: 1.9.1~1^2~158
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=f14c799ae7ff3be56c28f5694f04c03daff7708e

ao-tools: Add lots of compiler warning flags to ao-tools build

This catches some uninitialized variable errors which cause
ao-cal-accel to crash (fixes coming next)
