how to compile the odbc source?

hi all,
can somebody tell me, how to create a odbc interface? I tried to compile the odbc source, but a got the following error:
'psqlodbc.rc' can't be created.

I find out, that the source of win32.mak needs the 'psqlodbc.res' file, but the zipped file does no contained the file!
Where I can find or do I need the file?

can somebody help me?!?

thx
