Thank you.
I tested and I was disappointed.. I don't think it is worth adding a
new configuration for LTO using MSVC:

result:
size: win32 /O2 + LTO:    12.1MB (save 0.1 meg)
speed: win32 /O2 + LTO:   5.4s  (save 0.1 second)

+ the link-time took an eternity (something like 20 mins, could be
more) and close to 1 gig of RAM.
