libltdl7.x86_64: W: shared-lib-calls-exit /usr/lib64/libltdl.so.7.3.0 
address@hidden
This library package calls exit() or _exit(), probably in a non-fork()
context. Doing so from a library is strongly discouraged - when a library
function calls exit(), it prevents the calling program from handling the
error, reporting it to the user, closing files properly, and cleaning up any
state that the program has. It is preferred for the library to return an
actual error code and let the calling program decide how to handle the
situation.

libtool.x86_64: W: script-without-shebang /usr/share/libtool/config/ltmain.sh
This text file has executable bits set or is located in a path dedicated for
executables, but lacks a shebang and cannot thus be executed.  If the file is
meant to be an executable script, add the shebang, otherwise remove the
executable bits or move the file elsewhere.

Please fix, or otherwise comment.

Best regards,
Chris
