Synopsis - Issue Tracker

consider this input:
----8<----
#include <features.h>
#include <unistd.h>
----8<----

$ synopsis -p C -o /dev/null myinput.c

goes into an infinite loop:
   entering ASTTranslator::add_comments
   leaving ASTTranslator::add_comments
   entering ASTTranslator::update_position
   leaving ASTTranslator::update_position
<ctrl-C>
  leaving ASTTranslator::visit(PT::EnumSpec *)
 leaving ASTTranslator::visit(SimpleDeclaration)
leaving ASTTranslator::translate

I can't seem to reproduce this.
Can you please attach a preprocessed source ?

$ cat in.c 
#include <features.h>
#include <unistd.h>
$ cat in.c | gcc -P -E -dD -x c - > features-unistd.i

with STDC and STDC_HOSTED uncommented manually is attached.

Reduced testcase:

$ cat features-unistd.i
enum
  {
    _PC_LINK_MAX,
  };

Fixed as per rev:1824.
Thanks !
