Linux ecwav.panoptic.com 2.0.34 #31337 Mon Jun 22 18:25:40 EDT 1998 i486 unknown

>Description:
Building Apache 1.3.0 on my Linux 2.0.34 box yielded some unsatisfactory
results. Partly due to the configuration script's inability to detect
the need for -ldl for the --enable-shared=max, and the use of -lcrypt
(which is clearly documented as being needed for glibc 2.x, and my box
is a libc 5.x system, yet the configure script thinks I'm also glibc 2.x).
>How-To-Repeat:
Here is the configure command I used:
./configure --compat --prefix=/usr/www --proxycachedir=/usr/www/cache \
--enable-module=proxy --enable-module=expires --enable-module=log_referer \
--enable-module=status --enable-shared=max

---end-of-diff---
The first change would be more appropriate in helpers/TestCompile lib dl,
and have it properly recognize that Linux needs -ldl to build shared
libraries.
The second change should just require better identifying glibc 2.x systems
or Linux systems that require -lcrypt in general.
My patch was just a temporary fix to get Apache 1.3.0 to build cleanly
and to illustrate the problems I encountered.
Good luck, and if you need any more information, feel free to send me
e-mail.
