James and entropy,

It turns out that I had the Windows path before the CYGWIN path and there 
was a conflict with the 'find' command.  Because of that, the configure 
script couldn't do its job correctly.  When I put the CYGWIN path before the 
Windows path, everything compiled correctly.

By the way, the SQL Server DB-Library function dbfreelogin() is not 
available in FreeTDS.  Can you put this macro

#define dbfreelogin(x) dbloginfree((x))

into sqldb.h or sybdb.h.

Thanks,

DC
