> This patch has been pending for four months. Time for another go-round.
(I thought it was on hold pending further testing, oops)
> This patch does two things to get_compiler_info.
>
> First, I tweaked the "eval" mechanism to eval only the "set lines".
> This stops get_compiler_info from eval'ing random compiler diagnostics.
> This fixes a problem reported by Joel B.
>
> Second, as requested by Andrew C, this patch changes the implementation
> of gcc_compiled, hp_cc_compiler, and hp_aCC_compiler to be more local
> to gdb.exp, with no trace of these symbols in compiler.c and
> compiler.cc.
>
> Testing: I tested this on native i686-pc-linux-gnu with gcc 2.95.3
> and gcc 3.3.3. I also tested on native hppa2.0w-hp-hpux11.11
> with HP ansi-c and HP aCC. Joel B also tested an earlier version of
> this and says that it works for him.
Just so that there's no transition confusion here, yes, ok by me to
commit :-)
