There is an ODBC v2 driver for Microsoft Jet database on windows. (32 bit driver only) - A standard windows one. Having a look at it's exports, doesn't have SQLSetEnvAttr.
Regardless if we have an application, the above driver cannot be used since wine is using a function that is ODBC v3.0 only. The talk about adding support for fallback v2.0 functions is pointless if calling SQLConnection causes a crash.
As a note. The user with the issue, is using a .NET application to interface with an legacy database which only has a v2.0 driver available.
