Hello,

I've sent a mail here yesterday requesting for help in order to make
iodbc work in cygwin. I've investigated in the library code and found
something interesting :

In the log I've sent yesterday[1], each function name start with an « _ » 
wich does not appear in the sql driver library :

> objdump.exe -x /usr/lib/cygsqlite3odbc.dll | less
>           …
>         [   0] SQLAllocConnect
>         [   1] SQLAllocEnv
>         [   2] SQLAllocHandle
>         [   3] SQLAllocStmt
>         [   4] SQLBindCol
>         [   5] SQLBindParameter
>           …

The iodbc package contains the file « iodbc/henv.ci »[2] wich is actualy
an index of the declared function to call. There is a strange preprocess
instuctions at l79 wich needs to be completed in order to works in
cygwin :

> #define CLI    "SQL"

now you can rebuild the package and the odbc will work.

You can consider this mail as a bugreport (and I hope it will be
reported in the cygwin package).
