Hi,

it happens that some system headers on VMS have #pragma between parameters.  This is spotted by building the Ada runtime.

This patch simply handles them.

Manually tested by building for ia64-hp-openvms.
No regressions for c on x86_64-darwin.

Ok for trunk ?

Tristan.

	* c-parser.c (c_parser_parameter_declaration): Handle #pragma
	before a parameter.
