I don't know how to aply that. I only have binary version of the compiler.
Nor I am interested in substitute all the compiler instalations I can use.

I prefer to patch my own source when compiling with DJGPP:

In a general header I have put:

#ifdef __DJGPP__
#define atol myatol
#define atoi (int)myatol
#define strtol mystrtol
#endif

Then, all the source code stay untouched, except one file that includes
this:

#ifdef __DJGPP__

#undef atol        // now I have to call original ones
#undef atoi
#undef strtol

long myatol(const char *s) {
   while (isspace(*s)) s++;
   if (*s & 0x80) return 0;
   else return atol(s);
   }

long mystrtol(const char *s, char **endp, int base) {
   while (isspace(*s)) s++;
   if (*s & 0x80) {
      if (endp) *endp=s;
      return 0;
      }
   else return strtol(s,endp,base);
   }

#endif


Well, this works ok, but I have two questions:

1) How can I remove "assignment discards qualifiers from pointer target
type" warning at
"*endp=s" line?

2) Is it possible to know library version, to not use this patch when not
necessary?...
Something like #if defined(__DJGPP__) && (__DJGPPVER__<XXX)
