Comment(by JoelSherrill):
After the IRC tonight, I was looking at the tickets and this one caught my
eye. RTEMS via newlib does appear to have all of the powXXX variants. It
is in libm.a:
$ i386-rtems4.10-nm -g /opt/rtems-4.10/i386-rtems4.10/lib/libm.a |grep "T
po"
00000000 T powl
00000000 T pow10
00000000 T pow10f
00000000 T pow
00000000 T powf
So your probes have to be aware of which library the method is in. In
this case, it is libm.a, not libc.a. So I think this may be a non-issue
if you use the correct arguments.
And FWIW the definitive site for POSIX info is opengroup.org:
