     #include <stdlib.h>
     char *qecvt(long double number, int ndigits, int *decpt, int *sign);
     char *qfcvt(long double number, int ndigits, int *decpt, int *sign);
     char *qgcvt(long double number, int ndigit, char *buf);
 Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
     qecvt(), qfcvt(), qgcvt(): _SVID_SOURCE
