dnl Usage: ALIGN(bytes)
dnl
dnl Unicos assembler .align emits zeros, even in code segments, so disable
dnl aligning.
dnl
dnl GCC uses a macro emiting nops until the desired alignment is reached
dnl (see unicosmk_file_start in alpha.c). Could do something like that if
dnl we cared. The maximum desired alignment must be established at the
dnl start of the section though, since of course emitting nops only
dnl advances relative to the section beginning.
