Subject: Detect compile type (preprocess, compile, link) correctly.
X-Git-Tag: 0.01~81
X-Git-Url: https://ruderich.org/simon/gitweb/?a=commitdiff_plain;h=35a018278ad2fb931749f25d41bea0b7bd4f11e9;p=blhc%2Fblhc.git

Detect compile type (preprocess, compile, link) correctly.

The arguments to gcc (-E, -S, -c) and the file extension are used to
detect the correct type.

This fixes many false positives and a few false negatives.

Thanks to Bernhard R. Link for the idea.
