37d6a34e58 MSVC is a nimrod. (All verions 10.0 through 14.1) 
"(4074): error C4146: unary minus operator applied to unsigned type, result still unsigned"
So what?  Many programmers are much better than the typical Microsoft coder.
The C standard GUARANTEES that unsigned arithmetic uses two's complement,
ignores overflow, and the result is what the hardware adder produces.

2c2e108301 PE: fix comparison against a constant value 
... due to size always being assigned to right before this comparison,
and instead check against the RVA and size of the export directory
from the header. (note: this is still stricter than the Windows loader
which ignores all of these except the directory RVA, but if the name RVA
is invalid the PE was probably tampered with).
Change 'offset' to 'RVA' in exception message; this field is always an RVA
