I see bitcoin project trying to go -Wall (and related) free, POSIX, etc. So here are two from the unmodified 0.6.x branch (and likely master) that can be fixed...
net.cpp: In function 'bool GetMyExternalIP(CNetAddr&)': net.cpp:191: warning: 'pszKeyword' may be used uninitialized in this function net.cpp:190: warning: 'pszGet' may be used uninitialized in this function
I presume this applies to FreeBSD 9.x too. Thanks.
