svn commit: r591472 - /apr/apr/branches/1.2.x/configure.in

[wr...@apache.org]

Author: wrowe
Date: Fri Nov  2 14:25:16 2007
New Revision: 591472

URL: http://svn.apache.org/viewvc?rev=591472&view=rev
Log:
On Darwin 9.0 the NSLoad... dyld API is deprecated; use dlopen.

On HPUX 64bit PA-RISC or IA64... shl_ API is deprecated; use dlopen.
(Unless we can't in which case we'll jump on shl at the end.)

Heck, we can even shortcircuit os2's detection phase, it's custom.

Backport: 591191
