   ich habe ein Problem bei der Portierung von GAWK auf COHERENT 4.0,
   und zwar gibt es im File "awk3.c" einen Funktionsaufruf der
   Funktion "gcvt", diese Funktion ist in den Libs von Coh. 4.0
   nicht vorhanden.

   Kann mir jemand ein Beschreibung dieser Funktion geben,
   der Prototyp dieser Funktion lautet soweit ersichtlich:

   char *gcvt(double,int,char *)

Maine Manualseite vom NeXT lautet

ECVT(3)             UNIX Programmer's Manual              ECVT(3)

NAME
     ecvt, fcvt, gcvt - output conversion

SYNOPSIS
     char *ecvt(value, ndigit, decpt, sign)
     double value;
     int ndigit, *decpt, *sign;

     char *fcvt(value, ndigit, decpt, sign)
     double value;
     int ndigit, *decpt, *sign;

     char *gcvt(value, ndigit, buf)
     double value;
     char *buf;

DESCRIPTION
     Ecvt converts the value to a null-terminated string of ndi-
     git ASCII digits and returns a pointer thereto.  The posi-
     tion of the decimal point relative to the beginning of the
     string is stored indirectly through decpt (negative means to
     the left of the returned digits).  If the sign of the result
     is negative, the word pointed to by sign is non-zero, other-
     wise it is zero.  The low-order digit is rounded.

     Fcvt is identical to ecvt, except that the correct digit has
     been rounded for Fortran F-format output of the number of
     digits specified by ndigits.

     Gcvt converts the value to a null-terminated ASCII string in
     buf and returns a pointer to buf. It attempts to produce
     ndigit significant digits in Fortran F format if possible,
     otherwise E format, ready for printing.  Trailing zeros may
     be suppressed.

SEE ALSO
     printf(3)

BUGS
     The return values point to static data whose content is
     overwritten by each call.
