Hi Dan;

  I'm trying to remember to append my replies to the bottom of existing msgs 
:-)

  I added -ex to my script.

  I looked at gdb configure and the resultant Makefile for the specific error 
string...it is very hard for me to follow :-(

looking for termcap in configure:
*******************************************************
grep termcap ../gdb-6.0/configure
    configdirs="$configdirs libtermcap" ;;
    target_configdirs="$target_configdirs target-libtermcap target-winsup"
*******************************************************

looking for termcap in Makefile generates lots of output, but in that output, 
library is not found:

****************************************
grep termcap Makefile | grep library
<no putput>
****************************************

I changed the make install line for ncurses compile script to point to the lib 
generated by crosstool.  Looks like the libraries were written there 
successfully.  But the gdb compile still fails for the same reason.

:-(
