/* Patches to do automatic alignment of sections, based on the 
 *   requested alignment in the ELF object files, have been 
 *   incorporated into the mainline source code.  This patch gets
 *   around the fact that various linker versions treat the alignment
 *   in different ways.  By doing the alignment ourselves, we ensure
 *   that it is treated properly, and we get around operating system
 *   version checks for the linker.  Well, mostly.
 *
 * These changes were quite extensive and were completed on 6/25/97
 *   by Mark A. DeLoura.
