svn commit: r931697 - /subversion/trunk/configure.ac

[hw...@apache.org]

Author: hwright

New Revision: 931697

URL: http://svn.apache.org/viewvc?rev=931697&view=rev
Log:
Don't allow the use of APR 1.4.x.

An issue in APR prevents the various printf flavors from correctly parsing the
'%lld' format specifier.  From APR 1.4.x onward, this specifier is used on
OS X for APR_OFF_T_FMT, which we use extensively througout FSFS (and other
places too).  This parsing error causes segfaults in Subversion, rread the
issue for the gory details.

APR issue 48476 tracks this problem:
https://issues.apache.org/bugzilla/show_bug.cgi?id=48476

* configure.ac
  (APR_VER_REGEXES): Specifically disallow APR 1.4.x.
