Subject: MSVC++ 6

My program compiled with MSVC++ 6 (Enterprise) is almost 30% slower than the
same code with the same options compiled with MSVC++V5, which is a bit
disappointing.  The simple test I did was a fixed depth search for six middle
game positions.  More worrying than the decrease in speed is the number of nodes
to reach the fixed depth which have increased under VC6.

Usual type of program – PVS with hash tables.  Mixture of bitboards and offset
arrays.

What am I missing?
