So is it definitely a bug, and is it definitely possible to cross compile
gdb
for other systems than cygwin?

I'm trying to build a gdb debugger to be run on ARM Linux to debug apps
natively running under ARM Linux.  I will be building gdb using the
arm-linux-gcc cross compiler on an Intel box, so was trying to configure
with:
target=arm-linux
build=i386-linux
host=arm-linux
with-headers=<path to kernel sources>/linux-2.4.19/include

This will fail because it will report that with-headers is only supported
when cross compiling.  I'm muddled as to what target, build and host
therefore actually are?
