there is a bug in eglibc if it cant build without libc-libm-big
it should have not caused any undefined symbol failures because
all it should have done is not use double precision so your computations
will be less accurate.
Khem,
You are correct the problem is that if the libm-big option is not
specificed it grabs the dbl-wrap files for some sysdep function, but
still uses the dbl-64 functions for others.
Should I file an eglibc bug?
Sau!
