mdbtools/configure.ac
Evan Miller 148eed1546 Fix pkg-config Cflags 
Previously we needed the cflags to include the original HAVE_ICONV value
so that MdbHandle looked the same to client applications as it did to
the compiled library. Now we use a .in file for the header so that these
definitions are not necessary when the client is compiling.
