	This is because of the -ansi and -pedantic flags that are present in 
the Makefiles.  While these are useful during development, they should 
probably be turned off for releases -- many times the system headers 
themselves will cause piles of warnings.  It should build fine though.

	This is a bug in mail.c; here's a patch:

*** mail.c      25 Nov 2002 13:58:33 -0000      1.20
--- mail.c      3 May 2003 22:42:52 -0000
***************
*** 226,232 ****
     addrEnd = addr;

     /* ignore any ending white space */
!   while (addr >= addrStart && isspace((int)(unsigned 
char)*(addr-sizeof(*addr))))
       {
         addr--;
       }
--- 226,232 ----
     addrEnd = addr;

     /* ignore any ending white space */
!   while (addr > addrStart && isspace((int)(unsigned 
char)*(addr-sizeof(*addr))))
       {
         addr--;
       }



The existing code allows a comparison of the character before the 
'addrStart' address, which is bad.  On MacOS X, that character just so 
happens to be a space, and addr is decremented one too many times.  The 
result is a -1 being passed to xstrndup.

Thanks for that fix, I have committed it to the GNATS CVS repository.

Help with getting started on Mac OS X

[Doug McClure]

Hi,

I'm trying to setup gnats 3.999.2 on a Mac OS X Server but I'm having a 
few problems, and I'm wondering if anyone else has managed to get gnats 
up and running on X Server 10.2.5.

When I build gnats, I get a LOT of errors like these

...
regex.h:434:3: style of line directive is a GCC extension
regex.h:518:3: style of line directive is a GCC extension
regex.h:558:3: style of line directive is a GCC extension
In file included from edit.c:21:
gnats.h:407:3: style of line directive is a GCC extension
edit.c:22:3: style of line directive is a GCC extension
In file included from edit.c:22:
gnatsd.h:2:3: style of line directive is a GCC extension
gnatsd.h:23:3: style of line directive is a GCC extension
...

and some errors like this:

In file included from /usr/include/machine/types.h:30,
                  from /usr/include/stddef.h:63,
                  from ./../include/libiberty.h:129,
                  from gnats.h:37,
                  from edit.c:21:
/usr/include/ppc/types.h:75: warning: ISO C89 does not support `long 
long'
/usr/include/ppc/types.h:76: warning: ISO C89 does not support `long 
long'

In the end, gnatsd did compile, but when inetd tries to start it, I it 
crashes and I get a backtrace like this:

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_PROTECTION_FAILURE (0x0002) at 0x00091fff

  #3   0x0001a998 in get_responsible_addr (mail.c:251)
  #4   0x00003c64 in gnatsdChdb (cmds.c:662)

  #6   0x0000186c in _start (crt.c:267)
  #7   0x000016ec in start

If anybody has gotten it running on X Server, I'd appreciate any help 
you can give me
