4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync I/O Library. This file has compiler specifics for Microsft C as there is no
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync ANSI C standard for doing IO.
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync MSC - uses intrinsic functions and the optimize will remove the function call
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync We don't advocate putting compiler specifics in libraries or drivers but there
4fd606d1f5abe38e1f42c38de1d2e895166bd0f4vboxsync is no other way to make this work.
