@kindex --large-address-aware
@item --large-address-aware
If given, the appropriate bit in the ``Charateristics'' field of the COFF
header is set to indicate that this executable supports virtual addresses
greater than 2 gigabytes. This should be used in conjuction with the /3GB
or /USERVA=@var{value} megabytes switch in the ``[operating systems]''
section of the BOOT.INI. Otherwise, this bit has no effect.

@kindex --major-image-version
@item --major-image-version @var{value}
Sets the major number of the ``image version''. Defaults to 1.
