build problems

[Carsten Ilchmann]

Hi,

i have a problem with building xconq-7.3.3 on OpenBSD/i386 2.7

The compiler expects tcl.h and tk.h in subdirs tcl and tk of the working
directory. These do only exist if i extract the tcl/tk sources there.
I already have tcl/tk installed on my system. Headers are under
/usr/local/include/tcl8.3 and /usr/local/include/tk8.3 respectively.

Is there some way to pass these directories to configure, make or
whatever?
Without editing automatically created Makefiles if possible.

Thanks in advance.

Carsten
