AC_HAVE_LIBRARY is listed as an obsolete / deprecated macro in the AC
2.64 docs. So I think AC_CHECK_LIB is the better choice.

By the way, I used AC_CHECK_LIB instead of AC_HAVE_LIBRARY without any
good reason here. The only difference seems to be that the former
checks
for an actual function name in the lib. I don't know if/how the libpci
ABI actually changed in the past. Is their any common sense driving
such
a choice? AC_SEARCH_LIBS is sometimes recommended but I don't think it
matters for libpci.
