enabled by configuring with @option{--enable-obsolete}. Support will be

In order to compile GCC on an SGI running IRIX 5, the @samp{compiler_dev.hdr}

It is also available for download from

later, and use the @option{--with-gnu-ld} @command{configure} option

You need to use GNU @command{ar} and @command{nm},

also distributed with GNU binutils.

Configuring GCC with @command{/bin/sh} is @emph{extremely} slow and may
