The problem is that we could no longer use compile-time options. They used to be simple -DFOO macros in the cc command line, and quite many have been converted to "opt_foo.h" include options (so the Makefile dependencies will work again). However, converting every (major) #ifdef into a run-time configurable option will at least take a long time, and it doesn't seem to be *that* desirable at all. AT&T and SCO and [insert your favorite commercial vendor] had a totally different driving force to not use compilers -- they simply didn't want the users the source code. Thus, compile-time options were out of the question at all. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
