Prevent Python from stripping off the final newline of the main(){}

autoconfiguration tests. Some versions of gcc care enough about ANSI C
to complain about this.
 
Use the Linux install hierarchy conventions on other Unices as well.
 
XKeysymToString returns NULL on unknown keysyms, which is not a valid
std::string initializer.
 
There appears to be some disagreement regarding the second parameter
to iconv(). Some versions/installations have it as const, others don't.
Unfortunately, due to wonderful C++ brain damage, implicit conversion 
from const to non-const doesn't work here.
