Bug Description

Configure ok with:
./configure --with-tclconfig=/usr/lib/tcl8.5 --with-tkconfig=/usr/lib/tk8.5 CFLAGS=-i/usr/include/tcl8.5

When making, I got this error:

I did not have any problems with calfile.C on Linux Mint 13 64bit, gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5).

Still, I had to manually add
--with-tclconfig=/usr/lib/tcl8.5 --with-tkconfig=/usr/lib/tk8.5 CPPFLAGS=-I/usr/include/tcl8.5
to configure. I think it deserves an update to deal automatically with (apparently changed) file tree structure in Tcl/Tk 8.5.

Also, the requirement to add CPPFLAGS manually seems to be a bug - the Makefile generated even w/o this option includes
TCL_INCLUDE_SPEC = -I/usr/include/tcl8.5
line from tclConfig.sh but does not seem to use it.
