+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.
