Conditionally include paths.h, provide replacements for _PATH_LOG and _PATH_CONSOLE if it is absent. Provide dummy replacement for MSG_NOSIGNAL and LOG_PERROR. (log_write_async): Ignore SIGPIPE if MSG_NOSIGNAL is not defined. * src/main.c: Conditionally compile syslog-async stuff. * src/Makefile.am: Likewise. * configure.ac: Check for paths.h. Restore previous meaning of --enable-syslog-async. (DEFAULT_SYSLOG_ASYNC): New variable. Raise version number to 4.2.1. * doc/mailfromd.texi: Reflect above-mentioned changes. * gacopyz/server.c, gacopyz/gacopyz.c: Rename all sun to s_un and sin to s_in, to avoid name clashes. * NEWS (4.2.1): New entry. git-svn-id: file:///svnroot/mailfromd/tags/release_4_2@1535 7a8a7f39-df28-0410-adc6-e0d955640f24
