It seems that glibc has still problems with csqrt. See also http://sources.redhat.com/bugzilla/show_bug.cgi?id=2181 http://sources.redhat.com/bugzilla/show_bug.cgi?id=2182 . Therefore it may be useful to check in intrinsics/configure if libm is broken in the architecture used, and if so use the code in intrinsics/c99_functions.c . A possible solution for csqrt is shown in http://www-zeuthen.desy.de/~hvogt/gfortran/acinclude.m4.diff . It is better to be independend from glibc coming with the OS. This enables to install gcc4(gfortran) without patching libm if it has bugs. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24313
