I was trying to use some parts of the gpp library and
got some problems with including headers. I came to a simple program
that shows the problem:
Program:
#include <queue>
#include <complex>
int main ()
{
return 0;
}
Compiling with:
g++ -Wall -fsjlj-exceptions test.cpp -o f.exe -lm
and the output:
In file included from c:/djgpp/lang/cxx/cmath:7,
from c:/djgpp/lang/cxx/std/complext.h:34,
from c:/djgpp/lang/cxx/complex:7,
from test.cpp:2:
c:/djgpp/include/math.h:73: redefinition of `class exception'
c:/djgpp/lib/gcc-lib/djgpp/2.80/include/exception:20: previous
definition here
c:/djgpp/lib/gcc-lib/djgpp/2.80/include/exception:20: previous
declaration of `exception::exception(const struct exception &)' with
C++ linkage
c:/djgpp/include/math.h:79: conflicts with new declaration with C
linkage
c:/djgpp/lib/gcc-lib/djgpp/2.80/include/exception:20: previous
declaration of `struct exception & exception::operator =(const struct
exception &)' with C++ linkage
c:/djgpp/include/math.h:79: conflicts with new declaration with C
linkage
Switching the two include's:
#include <complex>
#include <queue>
int main ()
{
return 0;
}
Gives the output:
In file included from c:/djgpp/lib/gcc-lib/djgpp/2.80/include/new:9,
from c:/djgpp/lib/gcc-lib/djgpp/2.80/include/new.h:6,

I am a newbie with djgpp and I really don't understand.
Can somebody help me?
Thanks,
