Please allow me to correct.  The main program stack in VADS, e.g., is set
by a
configurable parameter in the v_usr_conf_b.a package body source file. 
There are other
configurable parameters there, such as the default storage_size for tasks,
etc.  Other
toolsets provide similar things.
In gnat for WinNT, Windows95, it is controlled by the specs file in either
the gnu_ld
or the ms_lnk directories, depending on the linker you're using.
