Subject: [PATCH] Fixes for PR258 and PR259. Functions with linkonce linkage
 are declared with weak linkage. Global floating point constants used to
 represent unprintable values (such as NaN and infinity) are declared static
 so that they don't interfere with other CBE generated translation units.
