Subject: compiling under minix?

Has anyone done this?  When trying to compile Linux under Minix
I get a missing "divi.." or something on link.  I assume these
to be soft floating point routines.

Why?  I have a problem with the harddisk driver under Linux
being to fast.  I had the same problem with minix, but being smaller
and slower, I was able to do enough compiling to put a delay in the
read function of wini.c.  Linux uses GCC, which use causes so much
disk reading to happen, that compiling is out of the question.

When compiling under minix, you are probably using an older version of
gcc (1.37.1 is the one that was on plains).  Older versions are unable
to inline the integer division routines, and use a function found in
gnulib for division instead.  Include gnulib in the final link, and all
should work. (Use the gnulib with minix - at least that one has been
tested with these functions).

			        About USENET

USENET (Users’ Network) was a bulletin board shared among many computer
systems around the world. USENET was a logical network, sitting on top
of several physical networks, among them UUCP, BLICN, BERKNET, X.25, and
the ARPANET. Sites on USENET included many universities, private companies
and research organizations. See USENET Archives.

		       SCO Files Lawsuit Against IBM

March 7, 2003 - The SCO Group filed legal action against IBM in the State 
Court of Utah for trade secrets misappropriation, tortious interference, 
unfair competition and breach of contract. The complaint alleges that IBM 
made concentrated efforts to improperly destroy the economic value of 
UNIX, particularly UNIX on Intel, to benefit IBM's Linux services 
business. See SCO vs IBM.
