# Note: This package has only been tested on Windows, and the pdcurses library
# it uses does not support Linux in console mode or mac OS X.

# Note: GDB has a bundled copy of readline that it uses.
# There is a --with-system-readline option we could try to use.

# Note: consider providing a mingw-w64 isl to gdb because its configure script looks for it
