Hi,

Related to https://bitcointalk.org/index.php?topic=28022.0 ;

Here are three patches that allow bitcoind to build and run on DragonFly BSD.

0001) bitcoind assumes a definition of BSD implies SO_NOSIGPIPE is available.
This is not true on NetBSD, OpenBSD, and DragonFly.

0002) main.cpp has: "char pchMessageStart[4] = { 0xf9, 0xbe, 0xb4, 0xd9 };"
Per discussion on the thread linked, leaving the signedness of pchMessageStart
is unsafe for values > 0x80. This patch specifies 'unsigned char' in main.cpp
and net.h.

0003) db.cpp has a number of uses of make_tuple and has 'using namespace std'
and 'using namespace boost'. Without qualifying make_tuple, std::make_tuple is
preferred, which is incorrect. This patch qualifies make_tuple.

Patches are from git format-patch and can be applied with git-am.

Thanks,
