NAME
 _MathIeeeDoubBasBase auto-open

 SYNOPSIS

 FUNCTION
 If the _MathIeeeDoubBasBase base variable is referenced (i.e.
 extern) but not declared then _MathIeeeDoubBasBase will be
 automatically declared in the ieeelib module of auto.lib.
 Additionally, auto.lib adds routines to the autoinit and autoexit
 sequences called by c.a that automatically opens
 "mathieeedoubbas.library" before _main and closes it after _exit.

 If the auto-open fails the program will be aborted before _main is
 ever called.

 The autoexit routine that closes the library first checks to see if
 the base variable is NULL and skips trying to close the library if
 so.

 NOTE
 DICE uses the autoinit feature to automatically open and close
 floating point libraries that are indirectly referenced by
 fp operations.

 EXAMPLE
 #include <stdlib.h>

 main()
 {
     double d;

     d = atof("1.234");
 }
