* Makeconfig (libunwind): New. (libgcc_eh): Add $(libunwind). (gnulib): Always set to -lgcc $(libgcc_eh). (static-gnulib): Always set to -lgcc -lgcc_eh $(libunwind). (libc.so-gnulib): New. * Makerules (LDLIBS-c.so): Use $(libc.so-gnulib) instead of $(static-gnulib). * configure.in (libc_cv_cc_with_libunwind): Set to yes if gcc uses -lunwind for static binaries. * configure: Regenerated.
