[commit] Use frame methods in i386 build

[Andrew Cagney <ac131313 at redhat dot com>]

Hello,

The attached fixes a few stray frame->pc, frame->frame and frame->next 
uses found when building i386 GNU/Linux native.

committed,
Andrew
2003-01-08  Andrew Cagney  <cagney@redhat.com>

	* gcore.c, i386-linux-tdep.c: Use get_frame_pc, get_next_frame and
	get_frame_base.
