POSIX.1-2001 and glibc use 'restrict' for these functions.
Let's use it here too.
glibc:
============================= ecvt
stdlib/stdlib.h:872:
char *ecvt (double value, int ndigit, int *restrict decpt,
int *restrict sign) THROW nonnull ((3, 4)) wur;
============================= fcvt
stdlib/stdlib.h:878:
char *fcvt (double value, int ndigit, int *restrict decpt,
int *restrict sign) THROW nonnull ((3, 4)) wur;
