verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository.

+// On ARM EABI targets this testcase will cause a warning to be emitted
+// whilst EABI attributes are being merged at link time unless
+// the --no-enum-size-warning option is passed to the linker. Whilst the
+// enum-size attributes should only be emitted if there are values of
+// enum type that can escape the compilation unit, gcc cannot currently
+// detect this; if this facility is added then this linker option should
+// not be needed. arm-*-linux*eabi should be a good approximation to
+// those platforms where the EABI supplement defines enum values to be
+// 32 bits wide.
