nse_fs.cc was forcing large files support, and it was broken on AIX due to this GCC bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=20366 Now we let autoconf handle setting the appropriate defines, and also check for this particular bug before defining.

dnl find_apr.m4 : locate the APR include files and libraries
|
|
dnl
|
|
dnl This macro file can be used by applications to find and use the APR
|
|
dnl library. It provides a standardized mechanism for using APR. It supports
|
|
dnl embedding APR into the application source, or locating an installed
|
|
dnl copy of APR.
|
|
dnl
|
|
dnl APR_FIND_APR(srcdir, builddir, implicit-install-check, acceptable-majors,
|
|
dnl detailed-check)
|
|
dnl
|
|
dnl where srcdir is the location of the bundled APR source directory, or
|
|
dnl empty if source is not bundled.
|
|
dnl
|
|
dnl where builddir is the location where the bundled APR will will be built,
|
|
dnl or empty if the build will occur in the srcdir.
|
|
dnl
|
|
dnl where implicit-install-check set to 1 indicates if there is no
|
|
dnl --with-apr option specified, we will look for installed copies.
|
|
dnl
|
|
dnl where acceptable-majors is a space separated list of acceptable major
|
|
dnl version numbers. Often only a single major version will be acceptable.
|
|
dnl If multiple versions are specified, and --with-apr=PREFIX or the
|
|
dnl implicit installed search are used, then the first (leftmost) version
|
|
dnl in the list that is found will be used. Currently defaults to [0 1].
|
|
dnl
|
|
dnl where detailed-check is an M4 macro which sets the apr_acceptable to
|
|
dnl either "yes" or "no". The macro will be invoked for each installed
|
|
dnl copy of APR found, with the apr_config variable set appropriately.
|
|
dnl Only installed copies of APR which are considered acceptable by
|
|
dnl this macro will be considered found. If no installed copies are
|
|
dnl considered acceptable by this macro, apr_found will be set to either
|
|
dnl either "no" or "reconfig".
|
|
dnl
|
|
dnl Sets the following variables on exit:
|
|
dnl
|
|
dnl apr_found : "yes", "no", "reconfig"
|
|
dnl
|
|
dnl apr_config : If the apr-config tool exists, this refers to it. If
|
|
dnl apr_found is "reconfig", then the bundled directory
|
|
dnl should be reconfigured *before* using apr_config.
|
|
dnl
|
|
dnl Note: this macro file assumes that apr-config has been installed; it
|
|
dnl is normally considered a required part of an APR installation.
|
|
dnl
|
|
dnl If a bundled source directory is available and needs to be (re)configured,
|
|
dnl then apr_found is set to "reconfig". The caller should reconfigure the
|
|
dnl (passed-in) source directory, placing the result in the build directory,
|
|
dnl as appropriate.
|
|
dnl
|
|
dnl If apr_found is "yes" or "reconfig", then the caller should use the
|
|
dnl value of apr_config to fetch any necessary build/link information.
