+ GCC also requires that the user has installed OSS646, the Execution

+ improved libc and RTLD.
+
+ In terms of tool usage, we want to use the standard link editor always,
+ and either the GNU assembler or the native assembler. With OSS646 the
+ native assembler has grown up quite a bit. Some of the specs below
+ assume that /usr/gnu is the prefix for the GNU tools, because thats
+ where the SCO provided ones go. This is especially important for
+ include and library search path ordering. We want to look in /usr/gnu
+ first, becuase frequently people are linking against -lintl, and they
+ MEAN to link with gettext. What they get is the SCO intl library. Its
+ a REAL pity that GNU gettext chose that name; perhaps in a future
+ version they can be persuaded to change it to -lgnuintl and have a
+ link so that -lintl will work for other systems. The same goes for
+ header files. We want /usr/gnu/include searched for before the system
