	Did my homework again, with the right level of caffeine, and by
re-reading the man page, herein quoted,

       Intel 386 Options

       These -m options are defined for the i386 family of computers:

       -mcpu=cpu-type
           Assume the defaults for the machine type cpu-type when
scheduling instructions.  The choices for cpu-type are i386, i486, i586,
i686, pentium, pentiumpro, k6, and athlon

           While picking a specific cpu-type will schedule things
appropriately for that particular chip, the compiler will not generate
any code that does not run on the i386 without the -march=cpu-type
option being used.  i586 is equivalent to pentium and i686 is equivalent
to pentiumpro.  k6 is the AMD chip as opposed to the Intel ones.

       -march=cpu-type
           Generate instructions for the machine type cpu-type.  The
choices for cpu-type are the same as for -mcpu.  Moreover, specifying
-march=cpu-type implies -mcpu=cpu-type.

	guess what? You're right...again! :)


	Nevertheless, will re-compile with CFLAGS explicitly demanding
-march=i686 and see what comes out from this hat, this turn...
