            Bug ID: 69549
           Summary: Named Address Spaces does not compile in C++
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: thiago at kde dot org
  Target Milestone: ---

It works in C:

$ cat test.c
__seg_gs char * ptr;
$ gcc -c test.c && echo Success
Success

But not in C++:

$ gcc -xc++ -c test.c
test.c:1:1: error: ‘__seg_gs’ does not name a type

Even though it's advertised as supported:

$ gcc -xc++ -dM -E /dev/null | grep SEG_GS       
#define __SEG_GS 1
