Glad to be of service.  I'd happily fix it if I had the foggiest idea why the 
#if 0 was in there in the first place.  (Was it chopped out because it 
doesn't work?  Because it took up too much space?  Should it be
#if CONFIG_DO_C99_MATH instead of #if 0?  Shouldn't strtold() be chopped out 
also if long double support is missing?)

I do intend to help audit the headers, I'm just working through my busybox 
to-do list first.  (The next low-hanging fruit was "sort", that lets me get 
rid of coreutils entirely in my development environment and 
still ./configure;make;make install everything except perl, which needs 
"comm".  I've already upgraded my little distro to a CVS snapshot of uclibc, 
and this problem was from that rather than 0.9.26.)
