"SectionAlignment
The alignment (in bytes) of sections when they are loaded into memory
It must be greater than or equal to FileAlignment. The default is the
page size for the architecture."

"FileAlignment
The alignment factor (in bytes) that is used to align the raw data of
sections in the image file. The value should be a power of 2 between 512
and 64 K, inclusive. The default is 512. If the SectionAlignment is less
than the architecture's page size, then FileAlignment must match
SectionAlignment."

For the import table use a case insensitive compare for the mscoree.dll
file name.
