You should be aware that NT on Alpha was *NOT* a LP64 operating system
(whereas Windows on IA64 is indeed LP64), and I'm presuming that the
"alpha-pe" is targeting the classical NT/Alpha configuration.  The ARC BIOS
that was used to load NT created a memory map that simulated a 32-bit memory
space, thus essentially making an Alpha behave much like an x86 -- well,
sort of.

A Wine compiled as Win64 will likely not be able to run Alpha NT binaries.
However, it might work reasonably well to compile apps with Winelib.
