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)(://(.*\.)?)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:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \
sysdeps/csky/configure \

sysdeps/riscv/configure \
sysdeps/unix/sysv/linux/csky/configure
# Omit changes that caused a pre-commit check to fail like this:

git checkout -f \

# Omit change that caused a pre-commit check to fail like this:

C2X (current version in git, postdating the most recent public draft
available as a PDF on the WG14 website) adds the interfaces from TS
18661-4, other than the reduction functions, as unconditionally
required and visible in <math.h> for hosted implementations; the
__STDC_WANT_IEC_60559_FUNCS_EXT__ macro is not included in C2X at all
(as the reduction functions aren't included at all, expected to end up
in a version of the TS updated to be relative to C2X).
This patch updates the glibc headers accordingly, following the same
pattern used for 18661-1 functions. As the only 18661-4 functions
currently supported are the exp10 functions that have been in glibc
for a very long time, this means that in fact __GLIBC_USE
(IEC_60559_FUNCS_EXT) ends up being used only to determine the
definition of __GLIBC_USE_IEC_60559_FUNCS_EXT_C2X, not yet in any
headers other than bits/libc-header-start.h.
(I hope to add the other 18661-4 functions to glibc at some point; the
main complication is the current lack of MPFR support for many of
these functions.)
Tested for x86_64.
* bits/libc-header-start.h (__GLIBC_USE_IEC_60559_FUNCS_EXT):
Update comment.
(__GLIBC_USE_IEC_60559_FUNCS_EXT_C2X): New macro.
* bits/math-finite.h [__GLIBC_USE (IEC_60559_FUNCS_EXT)]: Change
to [__GLIBC_USE (IEC_60559_FUNCS_EXT_C2X)].
* math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_FUNCS_EXT)]:
Likewise.

sysdeps/ia64/fpu/bits/math-finite.h exists and will be installed on
ia64, but during the build, the default math/bits/math-finite.h file
is used, which is wrong.
Fixes commit 0ac5ae2335292908f39031b1ea9fe8edce433c0f ("Optimize
libm").
