so, I now do get through the configure, but then "make" fails later with a
message that gcc cannot find guitcl.h. Indeed it's not on my system. Is this
supposed to be generated somehow?
In attempt to get through this, I configured:
../../gdb-7.6.50-2/gdb/configure CFLAGS="-g -O0" --without-tcl --without-tk
but that fails with the interesting double-negative error message.
checking for Tcl configuration... configure: error: no directory doesn't
contain tclConfig.sh
so... I still cannot compile gdb from source on cygwin. Any hints?
