Subject: Re:  __copysign redefinition

The problem is that the compilation line - at least that quoted in the bug 
report - does not include -fgnu89-inline.  This probably indicates glibc 
has been misconfigured or a broken compiler, although it could conceivably 
be a bug in the configure test for -fgnu89-inline support.

Removing a faulty line(libc_cv_gnu89_inline) from my custom configure.cache
solved this problem. -fgnu89-inline was included automatically
