Windows Link Errors Redux

I have gotten to the end of linking pgadmin3 on Windows XP with VS .NET,
and now I am encountering the following link errors:

pgAdmin3 error LNK2019: unresolved external symbol _regfree referenced
in function "private: void __thiscall wxRegExImpl::Free(void)"
(?Free(at)wxRegExImpl@@AAEXXZ)
pgAdmin3 error LNK2019: unresolved external symbol _regerror referenced
in function "private: class wxString __thiscall
wxRegExImpl::GetErrorMsg(int)const "
(?GetErrorMsg(at)wxRegExImpl@@ABE?AVwxString@@H(at)Z)
pgAdmin3 error LNK2019: unresolved external symbol _regcomp referenced
in function "public: bool __thiscall wxRegExImpl::Compile(class wxString
const &,int)" (?Compile(at)wxRegExImpl@@QAE_NABVwxString@@H(at)Z)
pgAdmin3 error LNK2019: unresolved external symbol _regexec referenced
in function "public: bool __thiscall wxRegExImpl::Matches(char const
*,int)const " (?Matches(at)wxRegExImpl@@QBE_NPBDH(at)Z)
pgAdmin3 fatal error LNK1120: 4 unresolved externals

These look like references to a regex library, but I don't remember that
being a requirement of either wxWindows or pgadmin. Any ideas?
