I am trying to use #include <vector> with g++ -mno-cygwin. My test
program is
$ cat test.c
#include <vector>
int main()
{ return 0;
}
which compiles fine with g++ without -mno-cygwin.
To try the same with -mno-cygwin, I copied the c++ include files from
c:\cygwin\usr\include\g++-3 to c:\cygwin\usr\include\mingw\g++-3 (as
described in
http://www.colomsat.net.co/freehost/ngiraldo/cppcygwin.html), and try to
compile again with -mno-cygwin. Now I get lots of errors:
$ g++ -mno-cygwin test.c

from test.c:1:

I guess the problem starts when new.h is included, which is not a mingw
include file.
I get the same error if I try to use the c++ include files that come
with the mingw distribution (using -I /mingw/include/g++-3, where /mingw
is where I installed mingw). I am not sure why I get the deprecated
warning, as I am using #include <vector>, not #include <vector.h>.
Does anybody know what is the correct way to include the c++ header
files with -mno-cygwin?
