FYI 1.0.3 has serious known bugs. If you want to stick with the 1.0.x
series you should update to the latest, 1.0.5, but that will probably
be the last release in the series. All new development is in 1.1.x.

Here's a summary of the expected failures with 1.1.8:

FAIL ./src/api/main.exe [status 1]
FAIL ./src/functional/wcstol-static.exe [status 1]
FAIL ./src/functional/wcstol.exe [status 1]
FAIL ./src/math/acosh.exe [status 1]
FAIL ./src/math/asinh.exe [status 1]
FAIL ./src/math/expm1l.exe [status 1]
FAIL ./src/math/j0.exe [status 1]
FAIL ./src/math/jn.exe [status 1]
FAIL ./src/math/jnf.exe [status 1]
FAIL ./src/math/lgamma.exe [status 1]
FAIL ./src/math/lgamma_r.exe [status 1]
FAIL ./src/math/lgammaf.exe [status 1]
FAIL ./src/math/lgammaf_r.exe [status 1]
FAIL ./src/math/sinh.exe [status 1]
FAIL ./src/math/sinhl.exe [status 1]
FAIL ./src/math/tgamma.exe [status 1]
FAIL ./src/math/y0.exe [status 1]
FAIL ./src/math/y0f.exe [status 1]
FAIL ./src/math/ynf.exe [status 1]
FAIL ./src/regression/malloc-brk-fail-static.exe [status 1]
FAIL ./src/regression/pthread-robust-detach-static.exe [status 1]
FAIL ./src/regression/pthread-robust-detach.exe [status 1]
FAIL ./src/regression/strverscmp-static.exe [status 1]
FAIL ./src/regression/strverscmp.exe [status 1]

I obtained the above form via "grep FAIL src/REPORT".

All of the math failures are very minor and can basically be ignored
unless you need the strict properties they're checking for. wcstol is
just reported because libc-test lacks some 64-bit versions of the
checks; it's not a bug in libc. main.exe fails because of some API
omissions for stuff that's stalled trying to coordinate with glibc,
IIRC. The pthread-robust failure is a bug that will be fixed in the
upcoming 1.1.9 release. strverscmp is also a bug with a patch pending
review. malloc-brk is a minor not-an-actual-bug issue.

I'm not sure right off what failures you should expect with 1.0.3. I
believe there will be a few additional ones, including some tests for
the serious bugs in the 1.0.x series that were fixed in 1.0.4 and
1.0.5.
