That would be my guess. Things get added to or modified in gcc. We
miss an<br>
option morphing and have to make a decision in retrospect. This is
unfortunately<br>
how a lot of the libgcc reorganization happened.<br>
<br>
I think enabling it by default is a good move. If it turns out to be
a problem,<br>
we can address that.<br>

Hello,<br>
<br>
the GCC implementation for destruction of thread-local objects
relies on the presence of a __cxa_atexit() support. Newlib
provides this function. It is also used on ARM EABI. Is
there a specific reason why this is not the default for all
RTEMS targets or in other words why don't we have in
gcc/config.gcc:<br>
