[PATCH/hack] Running from build dir again

[Keith Seitz <keiths@cygnus.com>]

Hi,

This gross hack allows insight to run from the build directory again.

Recent Tcl/Tk churn has broken this convenience, and, well, as hacky and
ugly as this is, it fixes it.

2001-09-19  Keith Seitz  <keiths@redhat.com>

	* library/main.tcl: Append iwidgets library path, if needed.
	* generic/gdbtk.c (gdbtk_init): Add TCLLIBPATH to iwidgets
	package index.
	Define IWIDGETS_LIBRARY in interpreter so that we can add
	this path to the auto_path at the right time later.
