Subject: HP-UX 11.00 patches for 0.9.3
Date: Wed, 19 Dec 2001 13:20:00 -0000
Message-id: <20011002180626.A90748@oolong.il.thewrittenword.com>
X-SW-Source: 2001/msg00549.html

HP-UX 11.00 has isinf() and isfinite() as a macro in <math.h>. Also
replaced the OS/2 hack with something hopefully better (untested).

BTW, any plans to upgrade to autoconf 2.5x?
