in gcc 3, the visibility attribute must be placed on both the declaration and on the definition. if it's omitted from the definition, the compiler fails to emit the ".hidden" directive in the assembly, and the linker will either generate textrels (if supported, such as on i386) or refuse to link (on targets where certain types of textrels are forbidden or impossible without further assumptions about memory layout, such as on x86_64). this patch also unifies the decision about when to use visibility into libc.h and makes the visibility in the utf-8 state machine tables based on libc.h rather than a duplicate test.
musl libc - a new standard library to power a new generation of
Linux-based devices. musl is lightweight, fast, simple, free, and
strives to be correct in the sense of standards-conformance and
safety.
musl is an alternative to glibc, eglibc, uClibc, dietlibc, and klibc.
For reasons why one might prefer musl, please see the FAQ and libc
comparison chart on the project website,

For installation instructions, see the INSTALL file.
Please refer to the COPYRIGHT file for details on the copyright status
of code included in musl, and the COPYING file for the license (LGPL)
under which the library as a whole is distributed.
Greetings!
As of the 0.8.0 release, musl is in _beta_ status. While some
interfaces remain incomplete or yet to be implemented, the ABI is
intended to be stable at this point, and serious efforts have been
made, using three separate test frameworks, to verify the correctness
of the implementation. Many major system-level and user-level programs
are known to work with musl, either out-of-the-box or with minor
patches to address portability errors; the main remaining applications
which definitely will not work are those which require C++ support,
which will be addressed during the 0.8 or 0.9 development series.
Included with this package is a gcc wrapper script (musl-gcc) which
allows you to build musl-linked programs using an existing gcc 4.x
toolchain on the host. There are also now at least two mini
distributions (in the form of build scripts) which provide a
self-hosting musl-based toolchain and system root: Sabotage Linux and
Bootstrap Linux. These are much better options than the wrapper script
if you wish to use dynamic linking or build packages with many library
dependencies.
The musl project is actively seeking contributors, mostly in the areas
of porting, testing, and application compatibility improvement. For
bug reports, support requests, or to get involved in development,
please visit #musl on Freenode IRC or subscribe to the musl mailing
list by sending a blank email to musl-subscribe AT lists DOT openwall
DOT com.
Thank you for using musl.
Cheers,
