--- Comment #16 from Dimitry Andric <dimitry at andric dot com> --- Created attachment 57639 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57639&action=edit Fix identifier poisoning in libcc1plugin and libc1plugin Here is another patch that can be committed separately. It fixes the direct inclusion of <vector> in libcc1plugin.cc and libcp1plugin.cc, and replaces it with INCLUDE_VECTOR before system.h.
