Don't give up.  The change I suggested in the previous post should allow 
you to build a little further.  With "--build=i486-slackware-linux" then 
'build' no longer is equal to 'host', and that is when the incorrect 
conditional statement applies:

if test "${build}" != "${host}"
then
   CC=${CC-${host_alias}-gcc}
   CFLAGS=${CFLAGS-"-g -O2"}
   CXX=${CXX-${host_alias}-c++}
   CXXFLAGS=${CXXFLAGS-"-g -O2"}
   CC_FOR_BUILD=${CC_FOR_BUILD-gcc}

By removing the "--build=i486-slackware-linux" I suspect you are no 
longer doing a cross compile which may lead to other problems in 
configure on your system.

Please change the following two lines

   CC=${CC-${host_alias}-gcc}
   CXX=${CXX-${host_alias}-c++}

to this

   CC=${CC-${host_alias-gcc}}
   CXX=${CXX-${host_alias-c++}}

and try configuring once again.  Report back if there are further 
issues.  There appear to be some FIXMEs in the configure code that 
probably haven't been resolved because no one has run across the issue 
yet.  You might be able to help.
