- Moved all the constructor code out of "stdlib_init_exit.c" and into the
files which initialize global data, such as the new "stdlib_program_name.c" and "stdlib_malloc.c". - Until I can find a way to invoke it from within the library, the __machine_test() function is no longer invoked. - Tagged global data with NOCOMMON attributes. - Added the __lib_init() and __lib_exit() functions, which are part of the thread-safe library and which can be used to hook up clib2 with standard Amiga shared library/device code. Some documentation on how to use them can be found in the <dos.h> header file. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@14999 87f5fb63-7c3d-0410-a384-fd976d0f7a62
