<p class="Body">
gcc-4.0.2 has been tested and works well.
</p>
<p class="Body">
gcc-3.[<a class="link" href="#123">123</a>] on all architectures with enabled global registers optimisation
(anything except x86) has known problems with global register variables,
see PR 7871. UQLX uses a workaround, the appended patch fixes gcc.
</p>
<p class="Body">
On <strong>ShoeString</strong> Linux use gcc2723 or gcc303 to compile.
</p>
<p class="Body">
config script attempts to guess affected compilers and disables the
optimisation by default (-DBROKEN_GREGS), this will result in slightly
slower code. gcc-3.4 and later do not suffer from this bug.
