Last change on this file since 270e3cc was 270e3cc, checked in by Joel Sherrill <joel.sherrill@…>, on Jul 11, 2000 at 2:56:04 PM

Patch rtems-rc-20000711-1-cvs.diff from Ralf Corsepius <corsepiu@…>
that decouples exec/ for the sh, m68k and i960 from targopts.h.

NOTE: The change to system.h is a hack to enable cpuopts.h
for some targets, but keep using targopts.h for others - I know it
does *not* work for sparc, mips, i386 and ppc. This will have
to be addressed as work continues on multilibing.
