[Xotcl] Bug: configure step assumes aolserver extensions if "aolserver" in $CWD

[jim at jam.sessionsnet.org]

Hi,

When configuring xotcl in any way whatsoever, it checks the $CWD variable
to determine if the string "aolserver" is anywhere in it. If so, it assumes
mistakenly in many cases that the build should include aolserver extensions.

The right way to do this is to add to configure.in a switch that allows the
builder to tell the configure step whether or not it should build with 
aolserver extensions.
