hi,all
   I want to build openldap on mingw and msys with back-sql, but the configure fails with following error message:
 
checking sql.h usability... no
checking sql.h presence... yes
configure: WARNING: sql.h: present but cannot be compiled
configure: WARNING: sql.h:     check for missing prerequisite headers?
configure: WARNING: sql.h: see the Autoconf documentation

in mingw/lib there is libodbc32.a, I copied and renamed it as libodbc.a
and checked it has 'SQLDriverConnect' function:
$ nm libodbc32.a | grep SQLDriverConnect
00000000 I
__imp__SQLDriverConnectW@32
00000000 T _SQLDriverConnectW@32
00000000 I __imp__SQLDriverConnectA@32
00000000 T _SQLDriverConnectA@32
00000000 I __imp__SQLDriverConnect@32
00000000 T _SQLDriverConnect@32
 
but configure still fails with above errors.
could anyone help me ? any commets are appreciated.
