shared lib dos filename style - one more question

[Danny Backx <danny.backx@scarlet.be>]

Hi,

I got a lot of help from several of you recently to point me in the
right direction. I am trying to get gdb to do the right thing when the
target is running on Windows Mobile (DOS filename style) and the host is
different (e.g. Linux).

This works, and I think I am close to having my patches in such a shape
that the libiberty maintainers will like them.

But the drawback for the gdb user is still that changing the variable
that steers this functionality often comes too late. The names are
processed when connecting to the target, changing the variable doesn't
affect gdb's operation any more. (See the session below, it also shows a
rather ugly workaround.)

My question : can anyone point me to where I should rerun some gdb
function when the gdb user changes the value of this variable ? I
already figured out that the shlib info gets passed when "solib_add" is
called, but is that what I need to rerun ?

Thanks,

	Danny

Note 1 : here is where I would like to interfere so the paths get
processed again, with the new value of have_dos_based_file_system .

Note 2 : disconnecting and connecting again is a workaround for not
having the functionality I still lack now.
