Re: -Weffc++ and STL

[wheeler at cipr dot no_spam dot rpi dot edu (Frederick W. Wheeler)]

I use the -Weffc++ option and the following long grep command to
eliminate warnings from the STL headers.  What you see here is part of
a makefile.  file.flint.o is the standard output of the compiler with
almost all warnings options turned on.  file.lint.o holds just those
warnings or errors that I want to see.

%.lint.o: %.flint.o
	-grep -v \
	  -e '/usr/stow/egcs' \
	  -e '/usr/stow/gcc' \
	  -e '/usr/local/include' \
	  -e 'instantiated from' \
	  -e '^        ' \
	  -e 'At top level' \
	  -e '^In instantiation of' \
	  -e '^In file included from' \
	  -e '__deque_iterator' \
	  -e '__list_iterator' \
	  -e '__default_alloc_template' \
	  -e '_Deque_base' \
	  -e '_Deque_alloc_base' \
	  -e '_Deque_iterator' \
	  -e '_List_base' \
	  -e '_List_alloc_base' \
	  -e '_List_iterator' \
	  -e '_Vector_base' \
	  -e '_Vector_alloc_base' \
	  -e '_Vector_iterator' \
	  -e 'In function' \
	  -e 'In method' \
	  -e 'In instantiation of' \
	  $< > $@
