504 # VGCONF_ARCH_PRI is the arch for the primary build target, eg. "amd64". By
505 # default it's the same as ARCH_MAX. But if, say, we do a build on an amd64
506 # machine, but --enable-only32bit has been requested, then ARCH_MAX (see
507 # above) will be "amd64" since that reflects the most that this cpu can do,
508 # but VGCONF_ARCH_PRI will be downgraded to "x86", since that reflects the
509 # arch corresponding to the primary build (VGCONF_PLATFORM_PRI_CAPS). It is
510 # passed in to compilation of many C files via -VGA_$(VGCONF_ARCH_PRI) and
511 # -VGP_$(VGCONF_ARCH_PRI)_$(VGCONF_OS).

523 # letters, and it also uses '_' rather than '-' as a separator, because it's
524 # used to create various Makefile variables, which are all in caps by
525 # convention and cannot contain '-' characters. This is in contrast to
