   Feature Test Macro Requirements for glibc (see
   feature_test_macros(7)):

       qecvt(), qfcvt(), qgcvt():
           Since glibc 2.19:
               _DEFAULT_SOURCE

ОПИСАНИЕ

       The functions qecvt(), qfcvt(), and qgcvt() are identical to
       ecvt(3), fcvt(3), and gcvt(3) respectively, except that they use
       a long double argument number.  See ecvt(3) and gcvt(3).
