As Dave Korn and Brian Dessent both pointed out, my problem was that gcc was compiling Hello.c with the default cdecl calling convention, but the library I wanted to link to uses the stdcall convention. Adding __stdcall to the function declarations in the header file eci.h fixed the problem. Dave suggested using the --enable-stdcall-fixup link option, which from the ld documentation did seem like it would do the trick, but I couldn't get it to work. I specified it to gcc as -Wl,--enable-stdcall-fixup, but still got the "undefined reference" error message.
