Yes, it seems that sqrt is expanded into inline code that always
issues the FSQRT instruction, and doesn't set errno. However, the
glibc manual seems to say that this should only happen under
"-ffast-math", and at least with GCC 2.95.4 on fencepost I cannot
reproduce this problem, it generates a call to the library function
under "-O0".
