I presume that the GDB at the following location isn't cygwin specific?
ftp.gnu.org/gnu/gdb/gdb-5.3.tar.gz

However, if you look at line 53 in gdb-5.3/readline/configure.in then
it issues the error given above if cross compiling for a non-cygwin
target.

Also my questions about build, host and target have been raised
because I'm unsure about the check for a cross compiler at line 123
in gdb-5.3/configure.in.  This checks whether the host and target
are the same thing, and only assumes it is a cross compiler if they
are different.  Why isn't this actually checking build and host?

Thanks.
