If it's used by a library other than libc, that means it needs to be exported at some symbol version - but it only needs a public version (as opposed to GLIBC_PRIVATE) if it might be used by user programs linked with glibc (if it's used in crt*.o, lib*_nonshared.a, or inline functions in installed headers, for example - or in libgcc.a, libstdc++.a, etc. (GCC static libraries)). > + gccfloat=`$CC $CFLAGS $CPPFLAGS -E -dM -xc /dev/null | grep __ARC_FPU_| wc -l` > + if test "$gccfloat" != "0"; then > + echo "glibc being configured for double precision floating point" preconfigure fragments should not print this sort of debugging message with "echo". If you feel such a message is important, use preconfigure.ac and print it with AC_MSG_NOTICE. -- Joseph S.
