egcs patch for glibc 2.1

This patch against egcs 971201 plus my glibc 2.1 patch will make
egcs to work again with glibc 2.1. I have tested it on both libc 5
and glibc 2.1. I think glibc 2.0 will be fine also.

BTW, there is a serious problem with 64bit sigset_t in glibc 2.1
and linux 2.1.71. It breaks all the old binaries which make system
calls with 32bit sigset_t. I think it should be fixed in the kernel
first.

Thanks.

this may be good luck (?), but I'm running Linux-2.1.71:

Linux version 2.1.71 (root@localhost) (gcc version egcs-2.90.20 971201 (gcc2-970802 experimental))

on my private box, together with  libc-971205 + glibc--971205.diff.gz, 
and have not seen any problems until now...

You are lucky. It turns out it is a glibc bug. Here is the patch for
glibc 2.1 971205. That is what happens when you mess around with those
bit fields.

Linus, I still think kernel should make sigset_t 32 bit for the older
system calls and make rt_sigset_t bigger for those new rt_sigxxxxx.
Otherwise, it will cause many trouble for code which uses big sigset_t
with sigxxxxx.

Thanks.

Re: egcs patch for glibc 2.1

[Jeffrey A Law]

        * filebuf.cc (filebuf::open): Call _IO_file_open if
        _G_HAVE_IO_FILE_OPEN is 1.

        * libio.h (_IO_fpos64_t, _IO_off64_t): Defined if
        _G_IO_IO_FILE_VERSION == 0x20001.

        * libioP.h (_IO_file_open): New declaration.

        * libio.h (_IO_FILE, _IO_stdin_, _IO_stdout_, _IO_stderr_,
        _IO_seekoff, _IO_seekpos): Add support for libio in egcs 2.1.
        * libioP.h (_IO_seekoff_t, _IO_seekpos_t, _IO_seek_t,
        _IO_seekoff, _IO_seekpos, _IO_default_seekoff,
        _IO_default_seekpos, _IO_default_seek, _IO_file_seekoff,
        _IO_file_seek, _IO_str_seekoff, _IO_pos_BAD, _IO_pos_as_off,
        _IO_pos_0): Ditto.
        * streambuf.h (streamoff, streampos): Ditto.

        * gen-params (__extension__): Use only if gcc version >= 2.8.

I've installed these patches (from your Dec 6th patch).
