TARGET_SCHED_DEFAULT can be defined in BOOT_CFLAGS if a different
default scheduling model is desired.
+As of GCC 3.5, GCC uses the UNIX 95 namespace for HP-UX 10.10
+through 11.00, and the UNIX 98 namespace for HP-UX 11.11 and later.
+This namespace change might cause problems when bootstrapping with
+an earlier version of GCC or the HP compiler as essentially the same
+namespace is required for an entire build. This problem can be avoided
+in a number of ways. With HP cc, @env{UNIX_STD} can be set to @samp{95}
+or @samp{98}. Another way is to add an appropriate set of predefines
+to @env{CC}. The description for the @option{munix=} option contains
+a list of the predefines used with each standard.
