[svn] * Makefile.in, configure, configure.in, docs/Makefile.in, src/Makefile.in: Added checks for the mail and sort programs. ./configure will abort if they're not found. * README: Removed the paragraph about news client software, as it's the same as the one in docs/NOTES. * TODO: Removed 'expiring by groups' and 'move some text from noffle.1 to noffle.conf.5'. * docs/NOTES: Changed the text about -DDEBUG to explain one should use './configure --enable-debug'. * docs/noffle.1, docs/noffle.conf.5: Minor fixes. Added myself and Jim Hague to the AUTHORS section :-) * src/client.h, src/common.h, src/configfile.h, src/content.c, src/content.h, src/control.c, src/control.h, src/database.h, src/dynamicstring.c, src/dynamicstring.h, src/fetch.h, src/fetchlist.h, src/group.h, src/itemlist.c, src/itemlist.h, src/lock.h, src/log.c, src/log.h, src/noffle.c, src/online.h, src/outgoing.h, src/over.c, src/over.h, src/post.h, src/protocol.h, src/pseudo.h, src/request.h, src/server.h, src/util.c, src/util.h: Added the <config.h> include. * src/content.c: Added missing include "content.h". Added a missing 'void' in the declaration of clearCont(). * src/fetchlist.c: Casted fetchlist.size to (size_t) in a call to qsort(), as qsort() expects a size_t. This removes a warning. * src/noffle.c: Made doRequested() static. Added missing void to enableCorefiles(). * src/log.c, src/protocol.c, src/online.c, src/pseudo.c: Added missing includes. * src/pseudo.c: Made genOv() and genPseudo() static. * src/server.c: Added missing void to postArts(). Made touchArticle() static. * src/util.c: Casted arguments of malloc() and memcpy() to size_t. * src/dynamicstring.c, src/itemlist.c, src/over.c, src/request.c, src/util.c: Removed casting of the result of malloc(). This is not necessary and can hide a missing include of <stdlib.h>.
