Summary:  cpp under OSX breacks .cplists by inserting #pragma at the start

Original Submission:  Processing of .cplist into .plist files on OSX is done 
using a line thus:

gcc -E -P -x c -traditional -DAPPLE xxx.cplist -o xxx.plist

The lateest version of cpp on OSX (gnu 3.3 based) inserts a #pragma
at the start of the resulting file. This looks liek:

#pragma GCC set_debug_pwd "/Users/pete/testapp"

The breaks the assumption made in the makefiles that the .plist file
will start with a single line '{' - which is then deleted using the 'sed 1d'
command. Thus the resulting .plist file in the application is invalid.

I cannt find an option to disable the insertion of the #pragma (nor any
reference as to why it is being inserted), so disabling the generation is
not that straightforward. It is, however, an easy matter to add a second
line of sed which will delete all #pragma lines from the output, and this
works as a solution. This can be accomplished by changing the cplist
rule in rules.make to:

%.plist : %.cplist
        $(ECHO_PREPROCESSING)$(CPP) 
                  $(filter-out $($<_FILE_FILTER_OUT_FLAGS),$(ALL_CPLISTFLAGS))
                  $($<_FILE_FLAGS) $< | sed '/^#pragma/d' > $@$(END_ECHO)

Arse - obviously the web submit has removed the indent tabs in the
last part of that! Please commit with appropriate tabs, thanks!
