mips build bug in 2.11.x

[mike stump]

I'm trying to build on the 2.11.x release branch:

gcc -W -Wall -O2 -o as-new app.o as.o atof-generic.o bignum-copy.o cond.o 
depend.o dwarf2dbg.o ecoff.o ehopt.o expr.o flonum-copy.o flonum-konst.o 
flonum-mult.o frags.o hash.o input-file.o input-scrub.o listing.o literal.o 
macro.o messages.o output-file.o read.o sb.o stabs.o subsegs.o symbols.o 
write.o tc-mips.o obj-elf.o atof-ieee.o itbl-parse.o itbl-lex.o itbl-ops.o 
e-mipself.o  ../opcodes/.libs/libopcodes.a ../bfd/.libs/libbfd.a 
../libiberty/libiberty.a
Undefined                       first referenced
 symbol                             in file
ecoff_directive_extern              tc-mips.o
ld: fatal: Symbol referencing errors. No output written to as-new
collect2: ld returned 1 exit status
make[2]: *** [as-new] Error 1

:-(

This is killed by:

        2001-06-07  H.J. Lu  <address@hidden>
        * config/tc-mips.c (mips_pseudo_table): Add "extern" if
        MIPS_STABS_ELF is defined.

from ecoff.c:

#ifdef ECOFF_DEBUGGING

void
ecoff_directive_extern (ignore)
     int ignore ATTRIBUTE_UNUSED;
{
[ ... ]
}

#endif /* ECOFF_DEBUGGING */

and in tc-mips.c:

#ifdef MIPS_STABS_ELF
  { "extern", ecoff_directive_extern, 0},
#endif


:-( Guess what, I bet ECOFF_DEBUGGING isn't defined for me and
MIPS_STABS_ELF is.

The question is, should I turn on ECOFF_DEBUGGING, or eject extern in
my case?  I'm building for mips-wrs-vxworks.  I'm trying out:

    { NULL, NULL, 0 },
  };
------------------------------

It gets me past the building phase.

I also noticed a bug just like this with .file for the pentium on
vxworks, it wanted dwarf2, and I was doing aout and stabs at the time.
It used to work, and now doesn't.  I'll report this separately.
