Subject: vfprintf.c:(.text+0xc6c): undefined reference to `__signbitl'

Hi out there,

I build the latest musl under

meres5@...ha:~/tmp$ uname -a
Linux alpha 2.6.32-5-powerpc64 #1 SMP Mon Oct 3 07:59:38 UTC 2011 ppc64
GNU/Linux

and got

meres5@...ha:~/tmp$ ld -o stdhello.static lib/crt1.o lib/crti.o stdhello.o
lib/libc.a lib/libgcc.a lib/crtn.o
lib/libc.a(vfprintf.o): In function `printf_core':
vfprintf.c:(.text+0xc6c): undefined reference to `__signbitl'
vfprintf.c:(.text+0xccc): undefined reference to `__fpclassifyl'

by linking static against musl a Hello sample.
I think this is not good. . .

I push on gcc with theese:

int __signbitl( long double x ) { return 0;}
int __fpclassifyl( long double x ) { return 0;}

then it worked fine - for this simple Hello :-)

Someone might have a look at math.h, and implement these
for this arch. . .

Regards
M5
