Jeff Hanes found a bug in the SVR2.0 libc/port/gen/atof.c; the
endptr was not being updated correctly by strtod in some cases.
This bug can be fixed as follows:

/*	@(#)atof.c	2.7	*/
...
#ifdef pdp11
...
		while (isdigit(c = *p) || c == '.' && !decpt++) {	/* DAG */
			p++;	/* DAG -- bug fix (increment done later) */
...
#else
...
		while (isdigit(c = *p) || c == '.' && !decpt++) {	/* DAG */
			p++;	/* DAG -- bug fix (increment done later) */
...
#endif
...
		switch (*++p) { /* process sign */	/* DAG */
...
