[AD] msvc7 compiler options

[aj <aj@xxxxxxxxxx>]

msvc7  compiler switch   /GL (Whole Program Optimization)
is there any reasons we are not using it ?
i have been modifying  makefile.vc  since 4.1.16  for this.
and had no ill effects.

also..   the  /arch:SSE     switch allows the compiler to produce SSE 
instructions.
( i could go further by saying SSE2,3 should also be added, but that would 
require more than the average users CPU).
SSE is available on Athlons, P3,P4.  which i would say is the average user CPU.
so as not to create a dependency on this instruction set, it could be added 
to the compiler options, much like the
TARGET_ARCH_EXCL=[cpu]   options.  ( /docs/alleg045.html )

also, the /G7 switch can be specified for Pentium4   (but somehow i feel 
this is not really appropriate yet, perhaps in the fullness of time it will 
see its way into makefile.vc  ;)
