So, apparently most close to success for now was:
CROSSOPT="-CpARMV7A -CfvFPV2 -dFPC_ARMHF"

It successfully produced object files, but ld refsuses to link them. 
Again, the message is:
pp.o uses VFP instructions, whereas .\pp does not
(lots of these repeated)

I'm guessing is that either some option is missing for ld to actually 
accept that VFP is present, or rather I need to rebuild my binutils for 
a different (hard fp) target?

(The exact call that fails now is arm-linux-ld.exe -s -L. -o .\pp 
.\link.res)


Thank you!

Nikolai
