Makefile is generated from Makefile.in when configuring sources.
There is script djconfig.sh for configuring sources in the same directory
as djmake.sh. There is also script djbuild.sh there which performs all steps
up to building binary packets (edit target name in djconfig.sh if needed,
before running it). I myself am lazy and use it (djbuild.sh).

Target should not be a problem at least for C. The defaults
with the current build is -march=i386 -mtune=i586 (code should
run on i386 and higher, but is optimized for i586 by default).
One can override these settings using command line options.
C++ standard library is another story and the binary version in
gpp412b.zip is compatible with processors beginning with i486.
