remctl 2.2

Thanks to Quanah's testing, I had accumulated various bug fixes for Solaris portability, the test suite, and builddir != srcdir builds. The interaction between gcc and glibc's sys/wait.h in unstable then caused a strange problem where the W* macros could not be applied to the int member of a const struct, so I added a workaround for that (and fixed various casting problems with printf on 64-bit systems).

In other words, no significant new functionality here, just a lot of minor bug fixes.

You can get the latest version from the remctl distribution page.
