Some C90 libm functions call fegetenv via libc_feholdsetround*
functions in math_private.h. This patch makes them call __fegetenv
instead, making fegetenv into a weak alias for __fegetenv as needed.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch). Also tested for ARM
(soft-float) that fegetenv failures disappear from the linknamespace
test failures (however, similar fixes will also be needed for
fegetround, feholdexcept, fesetenv, fesetround and feupdateenv before
this set of namespace issues covered by bug 17748 is fully fixed and
those linknamespace tests start passing).

* manual/argp.texi: Remove ignored LGPL copyright notice; it's
not appropriate for documentation anyway.
* manual/libc-texinfo.sh: "Library General Public License" ->
"Lesser General Public License".
2001-07-06 Andreas Jaeger <aj@suse.de>

* io/ftwtest-sh: More tests.
* misc/tsearch.c: Rewrite tdestroy_recursive.

nss/nss_files/files-hosts.c (Always use inet_pton).
* nis/nss_nisplus/nisplus-hosts.c: Likewise.
1997-05-30 09:50 Richard Henderson <rth@tamu.edu>
* manual/maint.texi: ECOFF hasn't been tested in ages and I don't
plan on doing so ever again. Don't say alpha-linuxecoff is known
to work.
* elf/dl-lookup.c: Include <alloca.h>.
* misc/tsearch.c: Include <string.h>.
* posix/execle.c: Include <alloca.h>.

parameters to network functions.
* sunrpc/pmap_rmt.c (clnt_broadcast): Likewise.
* sunrpc/svc_tcp.c (svctcp_create): Likewise with `len'.
(rendezvous_request): Likewise.
* sunrpc/svc_udp.c (svcudp_bufcreate): Likewise.
(svcudp_recv): Similar, but go through a local variable. The old code
used &xprt->xp_addrlen. Someone should determine if the type of the
structure member should be changed instead.
* sunrpc/xdr_rec.c (xdrrec_create): Expunge a ptr->int cast warning
and transform a nonsense for-loop to a closed form calculation.
(fill_input_buf): Another ptr->int warning.
* sysdeps/alpha/Makefile: Temporarily turn on -mieee globally. This
will last until I figure out how to build a parallel libm_ieee.

FP mode to round to nearest, no exceptions as for Intel.

(__setfpucw): Reformat.
* sysdeps/ieee754/huge_val.h: Change GCC's HUGE_VAL definition to use
a single DI-mode integer instead of bytes. This produces better code
on Alpha. Similar for HUGE_VALF.
