c - Use of type modifiers(near,far,huge) with normal variables -

-

i used type modifiers(far,near,huge) with normal variables rather pointers , found these pointer type modifiers applicable global normal variable error generated when used variable local block.

int near a,far b,huge c;  int main() {  int d,e,f;  // int near a,far b,,huge c; // long int near a,far b,huge c; // long long int near a,far b,huge c;  //printf("\n size of a=%d ,b=%d ,c=%d ,d=%d ,e=%d ,f=%d",sizeof(a),sizeof(b),sizeof(c),sizeof(d),sizeof(e),sizeof(f));  printf("\n address of a=%u ,b=%u ,c=%u ,d=%u ,e=%u,f=%u",&a,&b,&c,&d,&e,&f);   return 0;   }

why allowed global variable , not local variable. additionally, variable becomes i.e. becomes pointer,an integer greater range or entirely else.

near, far, , huge affect where, , in type of memory, variable stored. since local variables stored on stack, using these modifiers on local variables doesn't make sense.

note these features unique 16-bit dos platform. not used on modern systems -- can safely ignore them.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
