*still* isnan/isinf problems

[Graham Percival]

make distclean, cvs -q update.  No errors in ./configure.  OSX, fink 
patches.

offset.cc: In member function `bool Offset::is_sane() const':
offset.cc:91: error: `isnan' undeclared (first use this function)
offset.cc:91: error: (Each undeclared identifier is reported only once 
for each
   function it appears in.)
offset.cc:93: error: `isinf' undeclared (first use this function)
make[1]: *** [out/offset.o] Error 1
make: *** [all] Error 2


Are there any plans to fix this?  It's been about a month since I could 
last
build lilypond myself.

I could be missing some libraries or whatever, but in that case 
configure should
report it.
