[Bug c++/32371] New: #including <vector> brings keyword time in global namespace.

[olifant at gmail dot com]

The following code doesn't compile with g++:

  #include <vector>

  int time;

  int main() {}

Including the <vector> header brings the keyword "time" in global namespace. It
gives the following error:

  main.cpp:3: error: 'int time' redeclared as different kind of symbol
  /usr/include/time.h:187: error: previous declaration of 'time_t
time(time_t*)'

I'm not sure if that's a bug, but I don't think including <vector> should give
such results in C++. The time.h header, indirectly included via <vector> would
also be deprecated. The same code compiles fine with the comeau c++ online
test.

I'm not sure if gcc is responsible for the problem or if it's a problem with
the C library.

My gcc version info is:
