Upstream update. Signoff both, Allan This release contains bugfixes accumulated over the last 13 months since the release of 2.4 in September 2010. New in 2.4.2 2011-10-17: * New features: - The --with-pic configure option now supports a list of comma-separated package names. This can be used to build some static libraries with PIC objects while building others with non-PIC objects. - Initial support for Go, using the gccgo compiler. - On Mac OS X .dylib is now tried as well as .so with lt_dlopenext(). * Bug fixes: - The generic approximation of the command line length limit (when getconf is not available) works again. Regression introduced in v2.2.6-39-g9c3d4d8. - The bug that leaked developer tool paths into the release tarballs from ./bootstrap is fixed. - Improved support for the Cuda Compiler Driver (nvcc) on Darwin. - For GCC LTO support, the -fuse-linker-plugin switch is now also removed when computing compiler postdeps. * Important incompatible changes: - The undocumented hardcode_libdir_flag_spec_ld tag variable has been removed in favor of using hardcode_libdir_flag_spec with $wl set to empty. * Changes in supported systems or compilers: - Fixes for gfortran on Darwin, XL Fortran on GNU/Linux. - Support for FreeBSD 1.x (outdated since 1994) has been removed.
