build & c tools

[Salman]

I'm using standard gnu build programs
(ie automake-1.72, autconf-2.57, aclocal-1.72)
not the rtems ones (eg automake-rtems-automake-1.7.2)
are they any different ??

furthermore, should the c-tools be updated if one wants to build the latest rtems snapshot?
(i'm still using c-tools from rtems-4.5.0 decade)

i'm getting the following error, which I very much think are related to the top two issues
