Hi.

I have quite successfully built 4.6.0pre2 with gcc-3.2.2 for 
powerpc-rtems-mvme23xx, powerpc-rtems-svgm, i386-rtems-pc586.

A few things:

- the 'version.m4' files are not updated to 'pre2' (PR#392)

- if #377 is not merged, one hunk should still be applied (PR#393)

- PR#350 makes all 'make/custom/<bsp>.cfg' files consistenly
   include 'default.cfg' after defining RTEMS_CPU & friends
   (so these variables can be used in subsequent 'include()'
   statements)

- libnetapps still defines global symbols which

     a) clash against newlib (e.g. drand48, srand48)
     b) clash against libnetapps itself, e.g. there are
        multiple definitions of 'get_pty' within libnetapps.
     c) just don't belong into a system library every
        application is linked with, e.g.: 'error', 'debug',
        'die'.

    NOTE: a second patch in PR#350 also unbundles libnetapps
          from librtemsbsp so not everybody is forced to link
          against it.

PS & WOB:

Again a few goodies of global symbols defined by libnetapps
(list not complete):

a) drand48 mrand48 srand48

b) get_pty

c) error debug user modem magic temp2 ptys tp die
    output hostname linep lock line dirname trace
