The 2.7 branch has multiple heads


If you are have a problem building on OpenBSD and see output like this
while running configure:

checking curses.h presence... yes
configure: WARNING: curses.h: present but cannot be compiled
configure: WARNING: curses.h: check for missing prerequisite headers?
configure: WARNING: curses.h: see the Autoconf documentation
configure: WARNING: curses.h: section "Present But Cannot Be Compiled"
configure: WARNING: curses.h: proceeding with the preprocessor's result
configure: WARNING: curses.h: in the future, the compiler will take precedence

there is likely a problem that will prevent building python.  
If you see the messages above and are able to completely build python,
please tell indicating your version of OpenBSD
and any other relevant system configuration.

The build error that occurs while making may look something like this:

    /usr/include/sys/event.h:53: error: syntax error before "u_int"
    /usr/include/sys/event.h:55: error: syntax error before "u_short"

To fix this problem, you will probably need update Python's configure
script to disable certain options.  Search for a line that looks like:

    OpenBSD/2.* | OpenBSD/3.@<:@012345678@:>@)

If your version is not in that list, e.g., 3.9, add the version
number.  In this case, you would just need to add a 9 after the 8.
If you modify, you will need to regenerate configure
with autoconf.

If your version is already in the list, this is not a known problem.
