[6.3/MySQL Server 5.1] item_cmpfunc.h:1301: internal compiler error

[Gilles]

Hello

I updated the Ports collection on this 6.3 host, but it fails
compiling MySQL Server 5.1:

=======
In file included from item.h:2428,
                 from mysql_priv.h:749,
                 from sql_profile.cc:32:
item_cmpfunc.h:1301: internal compiler error: Illegal instruction: 4
Please submit a full bug report,
with preprocessed source if appropriate.
=======

Has someone seen this, and knows a work-around?

Thank you.
