Comparison warning from stl_deque.h

[John Yates]

The following program produces a warning about comparing signed and
unsigned quantities.

------------------- stl.cc -----------------------
#include <deque>

main()
{
	deque<char *>	aDeque;

	aDeque.erase(aDeque.begin(), aDeque.end());
}
-----------------------------------------------------

when compiled with "g++ -O -Wall -c stl.cc".

The compiler output is

---------------------------------------------------------
yates@titanic$ g++ -v -O -Wall -c stl.cc
