[Bug tree-optimization/45083] New: strange warning text from gcc

["tromey at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

While compiling gdb with a relatively recent svn trunk gcc, I saw:

gcc -g -O2   -I. -I../../archer/gdb -I../../archer/gdb/common
-I../../archer/gdb/config
-DLOCALEDIR="\"/home/tromey/gnu/archer/install/share/locale\"" -DHAVE_CONFIG_H

was declared here
cc1: all warnings being treated as errors


Those "$"s are strange to see, because they don't appear in the source.
I think it would be friendlier to emit "."s instead.

I will attach the .i momentarily.
