>Description:
	
gcc2.7.0 give the following warning when compiling strtoq.c:
cc -O -DNLS -DYP -DLIBC_SCCS -DSYSLIBC_SCCS -I/usr/src/lib/libc/include -D__DBIN
TERFACE_PRIVATE -DPOSIX_MISTAKE -DFLOATING_POINT  -c -p /usr/src/lib/libc/stdlib
/strtoq.c -o strtoq.po
/usr/src/lib/libc/stdlib/strtoq.c: In function `strtoq':
/usr/src/lib/libc/stdlib/strtoq.c:108: warning: integer overflow in expression

The line in question reads:
cutoff = neg ? -(u_quad_t)QUAD_MIN : QUAD_MAX;


>How-To-Repeat:
>Fix:
	
Removing the minus sign might help... it has no effect anyway (except for
the warning message).
