works on Red Hat Linux, i.e. that is based on glibc version 2.5.
Furthermore, this patch fixes a number of gcc 4.3.3 build errors in glibc 2.5
that occur on both x86 and x86_64. The older version of this library is still
useful for running Nix on a Red Hat host. Newer version of glibc fail to detect
the kernel's capabilities correctly (due to mad patches applied to the kernel
by Red Hat).
The individual changes are:
* Re-activated glibc 2.5 in all-packages.nix.
* Fix incomplete header search path in bootstrap tools.
Gcc-wrapper sets "-B<prefix>" to tell the compiler about its installation
root. Unfortunately, the setting doesn't add $gcc/lib/gcc/*/*/include-fixed
to the search path. That directory is required, however, because it contains
the system-specific "limits.h" file, and the glibc 2.5 builds tries to find
that file via #include_next.
* Support intrinsic functions like __signbit() or atof() correctly to avoid
compile-time conflicts.
* Switch to NPTL. Linuxthreads is no longer supported.
* Added a meta attribute to glibc package.
* Updated nixUnstable to version 0.13pre15614 from trunk. The previous version
failed regression tests.
* Fix more strict type checking in binutils since 2.18.50.0.3.
Without this patch, the build failed on x86, saying:
