This only should happen in C++ programs.  You can use the 
`-fconserve-space' switch to GCC to avoid it, but then you sacrifice some 
of the compiler diagnostics.  Look up the description of this switch in 
the GCC docs for more details.

This fragment requests a 1 MByte-long stack at run time.  If you run 
under DPMI, your default stack is fixed at 256KB max, unless you change 
it with the STUBEDIT program (which comes with DJGPP).
