I tried to use the stl vector class, and I got into problems:

The smallest program with the errors is:

#include <vector>

int main ()
{
	vector<int> v (10, 12);
	return 0;
}

I got the following errors from g++ -Wall test.cc:

c:/djgpp/lang/cxx/stl_vector.h:113: no type named `iterator_category'
in `int'
c:/djgpp/lang/cxx/stl_vector.h:113: no type named `value_type' in
`int'
c:/djgpp/lang/cxx/stl_vector.h:113: no type named `difference_type' in
`int'
c:/djgpp/lang/cxx/stl_vector.h:113: no type named `pointer' in `int'
c:/djgpp/lang/cxx/stl_vector.h:113: no type named `reference' in `int'
c:/djgpp/lang/cxx/stl_iterator.h: In function `{error}
iterator_category<int>(co
nst int &)':
c:/djgpp/lang/cxx/stl_iterator.h:127: warning: ANSI C++ forbids
typedef which 
does not specify a type
Abort!

I tried some things and found that the following program 
compiled well:

int main()
{
	int n = 12;
	vector<int> (10, n);
	return 0;
}

also the variants with other types were OK:

vector <double> v (10, 12.0), and vector<char> v (10, 'a'), ....

I searched in the archives and found similar (I believe the same)
problem (but no answers)  with vector class .

Is this a bug in stl?
Can it be fixed with some change in the header file?

Thank you very much in advance for your help.
