Confirmed. On Linux (should be also in Windows), the TREE_PUBLIC in
build_function_decl is set. On the other hand, Kai confirmed that in MinGW64
the same error occurs. It seems as if the TREE_PUBLIC is lost in between (the
error message is printed in tree.c's handle_dll_attribute).

Fails also with:
  gcc version 4.5.3 20110103 (prerelease) (GCC)
thus it is not a regression
(Obtainted from:
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Automated%20Builds/
; the "1.0" builds are for GCC 4.5.)

Thus, it does not seem to be an LTO problem or an -fwhole-file issue.
