Subject: Feature detect cpu_set_t (#221)
X-Git-Tag: M-staged-PR221
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f367e6af47c4ba71b0b285b2bc10a69fcd6f1baf;p=thirdparty%2Fsquid.git

Feature detect cpu_set_t (#221)

Some OS define this type but do not define __cpu_set_t_defined.
Use proper feature detection instead of relying on the macro.
