That's a good question.  I also noticed the c99 module being pulled in,
and I don't know offhand why this specific compiler isn't respecting
C99.

Sorry, I just sent the link for informational purposes.  The full
description of the problem is in the first message.  But basically, I'm
seeing this error:

  In file included from 
../../../../binutils-gdb/gdb/gnulib/import/scratch_buffer.h:9:0,
                   from ../../../../binutils-gdb/gdb/gnulib/import/glob.c:87:
  ../../../../binutils-gdb/gdb/gnulib/import/malloc/scratch_buffer.h:69:3: 
error: unknown type name ‘max_align_t’
     max_align_t __space[(1023 + sizeof (max_align_t)) / sizeof (max_align_t)];
     ^
  ../../../../binutils-gdb/gdb/gnulib/import/malloc/scratch_buffer.h:69:39: 
error: ‘max_align_t’ undeclared here (not in a function)
     max_align_t __space[(1023 + sizeof (max_align_t)) / sizeof (max_align_t)];

I'm also not sure what's happening here.  It seems to me that the stddef
module is not being picked up, or that max_align_t is not being declared
as it should.

I'll try to get in touch with the machine owner to check if it's
possible to gain access to it, so that I can investigate a bit further.

Thanks,
