glob.c build failure on RH el6

[Tom Tromey]

On this system:

$ uname -r
2.6.32-754.35.1.el6.x86_64

... the gnulib in gdb failed to build:

  CC       glob.o
../../../binutils-gdb/gnulib/import/glob.c: In function ‘next_brace_sub’:
../../../binutils-gdb/gnulib/import/glob.c:89: error: expected declaration 
specifiers before ‘__THROWNL’
[...]


I thought maybe the glibc version might be useful info:

$ rpm -q glibc
glibc-2.12-1.212.el6_10.3.x86_64


gdb uses:

    GNULIB_COMMIT_SHA1="776af40e09b476a41073131a90022572f448c189"


In the gcc -E output, I see that the gnulib cdefs.h replacement is not
being used -- I only see references like:

# 1 "/usr/include/sys/cdefs.h" 1 3 4

That defines __THROW:

#define __THROW __attribute__ ((__nothrow__))

... but not __THROWNL.

I've appended a patch (relative to the gdb import) that works.
I don't know the correct fix here.  I'd appreciate any advice.

thanks,
Tom
