Subject: Remove the following ./configure warnings:
X-Git-Tag: SQUID_3_2_0_1~511
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3cf1e8b61b6279a9820bd118afb9d8af3c140441;p=thirdparty%2Fsquid.git

Remove the following ./configure warnings:

  conftest.cpp:34:1: warning: "USE_DISKIO_AIO" redefined
  conftest.cpp:35:1: warning: "USE_DISKIO_DISKTHREADS" redefined

The patch allows Squid v3.1 to build on RHEL 5.4 which has autoconf v2.59.
Without the patch, USE_DISKIO_AIO is zero but the corresponding AIO files
are compiled, leading to errors. I do not know if other platforms are
affected.
