define(`HOST_DOS64')
dnl On DOS64 we always generate position-independent-code
dnl

dnl Usage: CALL(funcname)
dnl
dnl Simply override the definition in x86_64-defs.m4.

dnl Usage: FUNC_ENTRY(nregparmas)
dnl Usage: FUNC_EXIT()
dnl FUNC_ENTRY and FUNC_EXIT provide an easy path for adoption of standard
dnl ABI assembly to the DOS64 ABI.

dnl
dnl Used for private GMP symbols that should never be overridden by users.
