 /* Please note that these specs may look messy but they are required in
    order to emulate the SCO Development system as closely as possible.
    With SCO Open Server 5.0, you now get the linker and assembler free,
    so that is what these specs are targeted for. These utilities are
    very argument sensitive: a space in the wrong place breaks everything.
    So please forgive this mess. It works.

    Parameters which can be passed to gcc, and their SCO equivalents:
    GCC Parameter                SCO Equivalent
    -ansi                        -a ansi
    -posix                       -a posix
    -Xpg4                        -a xpg4
    -Xpg4plus                    -a xpg4plus
    -Xods30                      -a ods30

    As with SCO, the default is XPG4 plus mode. SCO also allows you to
    specify a C dialect with -Xt, -Xa, -Xc, -Xk and -Xm. These are passed
    on to the assembler and linker in the same way that the SCO compiler
    does.

    SCO also allows you to compile, link and generate either ELF or COFF
    binaries. With gcc, we now only support ELF mode.

    GCC also requires that the user has installed OSS646, the Execution
    Environment Update, or is running release 5.0.7 or later. This has
    many fixes to the ELF link editor and assembler, and a considerably
    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 because 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
    header files. Hence the -isystem /usr/gnu/include in the CPP_SPEC.
    We get /usr/gnu/lib first by virtue of the MD_STARTFILE_PREFIX below.
