sqrtl/ldexpl prototypes

[Willem Konynenberg]

Hello,

I have a question on the math interfaces.

I am using some interfaces such as ldexpl and sqrtl.
On some platforms, these are defined as inlines via math.h.
No problem there.
On some other platforms, however, they are not defined
as inlines, and as far as I can tell, math.h provides no
prototype declaration for these functions in that case.

I had thought (lacking an appropriate standard document to refer
to, my books are too old for this) that including math.h would
provide the necessary prototypes to be able to use these functions.
Is that an incorrect assumption, or is there perhaps some
omission in the math prototypes?

I tried to search the glibc source to see what is where, but I
couldn't find any prototypes for functions like sqrtl/ldexpl,
only the base sqrt/ldexp.

Currently, I am getting complaints about compiler warnings
from someone trying to compile the software on PowerPC.

(I searched the 2.2.3 source, because that is what I have here,
 but the compile attempts are with 2.1.3)

Thanks for any help.
