/* The following definitions are used in libgcc2.c with the __main
function. The _SHR symbol is used when the sharable image library
for libg++ is used - this is picked up automatically by the linker
and this symbol points to the start of the __CTOR_LIST__ from libg++.
If libg++ is not being used, then __CTOR_LIST_SHR__ occurs just after
__CTOR_LIST__, and essentially points to the same list as __CTOR_LIST. */
