Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:

(_nl_C_LC_NUMERIC): Use `not_available' for grouping value.
* nss/nsswitch.conf: Example configuration file.

for nss_db.
* nss/Makefile (distribute): Add nsswitch.conf and db-Makefile.
1996-08-28 Paul Eggert <eggert@twinsun.com>
* C-messages.c (_nl_C_LC_MESSAGES): Set yesexpr to "^[yY]" and
noexpr to "^[nN]"; this conforms to POSIX.2.
* C-time.c (_nl_C_LC_TIME): Change %d to %e in d_t_format, to
conform to POSIX.2.
1996-08-28 Paul Eggert <eggert@twinsun.com>

mon_grouping, int_frac_digits, frac_digits, p_cs_precedes,
p_sep_by_space, n_cs_precedes, n_sep_by_space, p_sign_posn, and
n_sign_posn to CHAR_MAX, as required by the POSIX Standard.
Wed Aug 28 23:12:28 1996 Ulrich Drepper <drepper@cygnus.com>

`_nss_db_*' instead of `_nss_files_*'.
(lookup): `parse_line' returns 1 if succesful.
* nss/nss_files/files-service.c (servbyname): Key for database
must also contain protocol names.
(servbypt): Likewise.
Test must also check for protocol. Add `proto' argument.
Tue Aug 27 09:56:13 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>

and RPC errors that indicate that the socket server is not really
present and able to do its job, turn the error into EPFNOSUPPORT.
* sysdeps/generic/sbrk.c (__sbrk): Get kernel brk address
always only if in static libc or if statically linked program
