From 80afd15ee08885883624baa12d16ae79050da580 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Arrange for C compilation throughout the tree to get 
 C_SWITCH_SYSTEM from the configuration files. 	* configure: Extract
 C_SWITCH_SYSTEM from the machine and 	system-dependent files, and save it in
 the top-level Makefile. 	* Makefile.in (C_SWITCH_SYSTEM): New flag for
 configure to edit. 	(lib-src/Makefile): Edit C_SWITCH_SYSTEM into
 lib-src/Makefile.
