building odbc driver from sources with debug information -win32

[Ajit Aranha]

How do I build the odbc driver from sources on win32 with enabling debug
information.
I am familiar with the build scripts,and setting up the build
environment but haven�t been able to figure out how to build with debug
information.(I have built the regular release build.)
Regards,
Ajit
P.S. I am trying to debug a crash that occurs under load.
