Yes, this bug still exists in egcs.

It certainly shouldn't be data_section!

Seems to me it should be calling one of the various other functions
in varasm instead of readonly_data_section directly.

Like variable_section or assemble_variable.  It would take some tweaking
of the objc-act.c code, but it shouldn't be all that hard.

That code all looks pretty bogus to begin with; I think it should build
up a VAR_DECL for the constant itself, set TREE_READONLY to one, then
call into assemble_variable.  You can then get rid of the gunk to align
the section, and output of the constant (you still need the assemble_external).

Can you do this, test it and send me the patch?
