util/spkmodem-recv: warn on unhandled exit error
my style of C programming is this: always return errno upon exit from the program, or from a thread. handle errno in the calling/forking function. returning errno at the end of main has this intention: if an unhandled error occured, the program exits with non-zero status. a correctly written program should *never* return non-zero at the end of main, and if it does, this indicates a bug in the code (per my code style / philosophy). so, warn the user with a message if this occurs. the intention is that this message should never be printed. do not use assert() for this. i don't believe in that. such a test should always be present, for everyone.
