The file 'libs/sofia-sip/s2check/exit77.c' was moved in order to
silence the warning and to keep the build working. There might be a
build problem that results from this file move, but after serveral
build tests I have not found one. The contents of the file are
specifically for the make check target, so I believe it would be
highly unlikely to cause problems with any production feature.

Latest automake will detect then warn if the Makefile uses source
files that are in subdirectories, but the subdirs option is not
set. In the FreeSWITCH build system the current expected behavior is
to expect the subdirs option to be enabled.
