#28 Fix GCC 2.95 compile errors

[Christopher Nelson]

For an old embedded Linux system, we're stuck with GCC 2.95 which complains about several PERROR() macro calls saying:

protocol.c:845: unterminated string or character constant
protocol.c:291: possible real start of unterminated constant

This patch fixes those warnings in PTPd 1.0.0

Fix GCC 2.95 warnings

[George Neville-Neil]

This should have been fixed in the move to syslog.
