Log Message:
Pull up revisions 1.52-1.58 (requested by christos in ticket #1967):

1.52:
define a __used attribute (empty for gcc<2.7)

1.53:
The __used__ attribute first appeared in gcc 3.1, not in 2.7, according
to the gcc expertise.  Fixes build problem for the vax port, which still
uses gcc 2.95.3.

1.54:
add __DECONST()

1.55:
DECONST->UNCONST

1.56:
a little safer impl of __UNCONST, using __typeof__ if __GNUC__.

1.57:
__UNCONST: add parens around a macro argument.

1.58:
kill gcc specific version of __UNCONST. Does not work to unconst
const char *foo[];
