You're confusing version numbers.  DJGPP is at version 1.07.  GCC is
at version 2.2.2.  GAS is at version 1.38.1, etc.  1.07 should work
under DesqView no problem.

Yes, -O2 is supported.  gcc-2.2.2 comes with complete FSF documentation.

Some math functions have been fixed in 1.07 - please recheck the patches
with djdev107.zip before sending them to this list.
