NT-based platforms seem to have a compatibility hack within user32 or
thereabouts that looks at the PE optional header version fields. I ran an
unmodified user32_crosstest.exe with your test through the test bot, which
showed that LoadImageA on platforms older than Win2k3 fail with the test
parameters, while Vista and newer platforms crash.

After using a PE editor on user32_crosstest.exe to change the required OS
version, image version, and subsystem version to match Okad2's values, running
that executable through the test bot showed that LoadImageA succeeds for the
given parameters on all platforms except Win98.

Do we want to replicate the exact compatibility check, or should we just change
LoadImage to succeed/fail as it does on Win2k3 and older?
