Thanks for the pointer, seems useful, I'll give it a try.

Well, I had missed the --disable-gdb option, and so for me a top-level
./configure would always recurse into gdb/, and gdb/configure.ac does
check for ncurses.

I'll give it a try with --disable-gdb and "make all-gdbserver" as
suggested by the documentation.

Thanks !
