I was probably unclear in my mail.
It was cpuflags (pkgsrc's devel/cpuflags) that added the "-O2 
-march=pentiumpro" to the compile line, as the result of being .sincluded 
in /etc/mk.conf. I did (almost) nothing else except launching the command I 
wrote before.

I did not customize the floppies. I launched the build but, since it bailed 
out telling me the floppy image size was too big, I had to remove one of 
the floppies (rescue-small) from the build. In other words, except the (2? 
3?) Makefile-s modified to exclude rescue-small from build, no file is 
different from the source tarballs provided on the FTP site.

I think it should, after all the toolchain should be expected to work 
correctly, unless I am misunderstanding something.

I have a PentiumII machine which works just fine. As for the CFLAGS, how 
can I know if they got overwritten somehow?

Thank you.
