# In general, GPLv2+ is used by programs, LGPLv2+ is used for
# libraries.
#
# LGPLv2+ with exceptions is used for things that are linked directly
# into dynamically linked programs and shared libraries (e.g. crt
# files, lib*_nonshared.a).  Historically, this exception also applies
# to parts of libio.
#
# GPLv2+ with exceptions is used for parts of the Arm unwinder.
#
# GFDL is used for the documentation.
#
# Some other licenses are used in various places (BSD, Inner-Net,
# ISC, Public Domain).
#
# HSRL and FSFAP are only used in test cases, which currently do not
# ship in binary RPMs, so they are not listed here.  MIT is used for
# scripts/install-sh, which does not ship, either.
#
# GPLv3+ is used by manual/texinfo.tex, which we do not use.
#
# LGPLv3+ is used by some Hurd code, which we do not build.
#
# LGPLv2 is used in one place (time/timespec_get.c, by mistake), but
# it is not actually compiled, so it does not matter for libraries.

%description
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

%description devel
The glibc-devel package contains the object files necessary
for developing programs which use the standard C libraries (which are
used by nearly all programs).  If you are developing programs which
will use the standard C libraries, your system needs to have these
standard object files available in order to create the
executables.

use the standard C libraries.

Summary: Compatibility support for linking against libpthread_nonshared.a.

%description -n compat-libpthread-nonshared
This package provides compatibility support for applications that expect
libpthread_nonshared.a to exist. The support provided is in the form of
an empty libpthread_nonshared.a that allows dynamic links to succeed.
Such applications should be adjusted to avoid linking against
libpthread_nonshared.a which is no longer used. The static library
libpthread_nonshared.a is an internal implementation detail of the C
runtime and should not be expected to exist.
