Subject: Implement the --fatal-errors command line option
X-Git-Tag: 0.14.alpha0~18^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=03397f1dae5df08467644106cf2c2083ed77806c;p=cython.git

Implement the --fatal-errors command line option

If enabled, it will abort on the first error occured. Just like "gcc
-Wfatal-errors".
