[named-addr-spaces-branch][Patch,committed] Make __ea a C only keyword

[Michael Meissner]

Because the named address support has not been added to C++ yet, and libstdc++
contains an include file with a __ea identifier, change named address space
keywords to C only for the time being.

2008-12-05  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* c-common.h (ADDR_SPACE_KEYWORD): Set the disable flags to
	D_CONLY|D_EXT so that the source ell_integral.tcc in libstdc++
	which has a __ea identifier builds.
