 Because standart says:
 The radix character is determined by the current locale.
 Follow this way: check LANG, then set locale.

 I create a little test proram:
 ---- test.c ---
 #include <stdio.h>
 #include <stdlib.h>
   
 int main(void)
 {
         char buff[255];
         double value = -1000.010101011;
         char *link;
 
         link = buff;
         gcvt(value, 16, link);
         printf("%s\n", buff);
   
         return 0;
 }
 
 ---- test.c ---
 $ cc -Wall -g 1.c -o 1
 $ LANG=C ./1
 -1000.010101011
 $ LANG=ru_RU.KOI8-R ./1
 -1000,010101011
 
 Looks like it works, isn't it?
