Dear users,
when you try to compile a program that needs to include the vector and the
math.h files, you have some error.
DJGPP 2.8.1 in dos environment.


Examples.
try to compile this simple source

#include <vector>
#include <math.h>

main()
{
}


you get a lot of errors-

c:/djgpp/lib/gcc-lib/djgpp/2.81/include/exception(20) Error: previous declara
c:/djgpp/include/math.h(79) Error: conflicts with new declaration with C link
c:/djgpp/lib/gcc-lib/djgpp/2.81/include/exception(20) Error: previous declara
c:/djgpp/include/math.h(79) Error: conflicts with new declaration with C link
There were some errors


this because there's a multiple declaration in either files
in <vector>
class exception


in <math.h>
struct exception



The only workaround is to define EXCEPTION before the <vector> include

#include <math.h>
#define __EXCPTION__
#include <vector>

main()
{
}


Is this a feature or a bug ?
TIA
