For 5.0.0 and 5.0.2, you must install TLS597 from ftp.sco.com/TLS.
5.0.4 and later do not require this patch.
The native SCO assembler that is provided with the OS at no charge
is normally required. If, however, you must be able to use the GNU
assembler (perhaps you have complex asms) you must configure this
package @samp{--with-gnu-as}. To do this, install (cp or symlink)
gcc/as to your copy of the GNU assembler. You must use a recent version
of GNU binutils; version 2.9.1 seems to work well. If you select this
option, you will be unable to build COFF images. Trying to do so will
result in non-obvious failures. In general, the "--with-gnu-as" option
isn't as well tested as the native assembler.
@emph{NOTE:} You must follow the instructions about invoking
@samp{make bootstrap} because the native OpenServer compiler builds
a @file{cc1plus} that will not correctly parse many valid C++ programs.
