Issue #5491 has been updated by The Written Word Inc.


For compile.c, we have:
  #include "ruby/ruby.h"
  #include "vm_core.h"
    #include "thread_pthread.h"
      #include <pthread.h>
        #include <pthread_exception.h>
          #include <c_excpt.h>

So, if you #undef leave and #undef except after #include <pthread.h> in thread_pthread.h, that's a solution as well.

Bug #5491: build failure on Tru64 UNIX 5.1
http://redmine.ruby-lang.org/issues/5491

Author: The Written Word Inc
Status: Open
Priority: Normal
Assignee: 
Category: build
Target version: 1.9.2
ruby -v: UNKNOWN


Building 1.9.2 with latest svn revision at 33531 produces a build error because <c_except.h> defines leave and except:
  /* definitions of keywords and intrinsic function names */
  #ifndef __cplusplus
  #define try                    __builtin_try
  #endif
  #define except                 __builtin_except
  #define leave                  __builtin_leave
  #define finally                __builtin_finally
