Hi,

I think that I've found something wrong.
Assuming the following case:

./configure --with-includes=/usr/local/include --with-libs=/usr/local/lib

and some libraries and header files are in /usr/local/lib and
/usr/local/include respectively; in example, odbc library.

The newly created head file has an empty ODBCINC though ./configure said
"yes" for sql.h.


In configure.in:

	ODBCINC=
	if test -n "$odbc_includes"; then
	    if test -d "$odbc_includes"; then
	        ODBCINC="-I$odbc_includes"
	    else
	        AC_MSG_WARN([*** ODBC includes directory $odbc_includes does not
	exist.]
	)
	    fi
	fi

At this point, ODBCINC is empty because --with-odbc-includes was not given.

	AC_SUBST(ODBCINC)

	ac_save_cppflags="$CPPFLAGS"   

However, ./configure has found "sql.h" in /usr/local/include because this
directory was given as "--with-includes".

	CPPFLAGS="$CPPFLAGS $ODBCINC"
	AC_CHECK_HEADERS(sql.h)
	CPPFLAGS=${ac_save_cppfl


As a result, odbc driver compilation failed.
This case may occur in all other substitutions.

Just my thought.

Yours,
Huidae Cho
