The patch from revisions 1.138 to 1.139 of configure.in is:

853c1139,1142
< AC_CHECK_LIB(ieee, __fpu_control)

The check-in comment is "Only link with -lieee when it's necessary".
If it only checks for -lieee when the __fpu_control function is
defined, perhaps the function disappeared in glibc 2.1.
