Yes, i also had this problem!
I did i dirty trick to make these calls work:
By changing every call to "sqlg????" in the DB2 Precompiled output to 
"sqla????"
These are the API Calls for C-Programs.

I did many test and everything seems to work fine, although i'm not really 
pleased about this aproach.
We could ask IBM for an Enhancement of the Preprocessor to accept the Target 
"OPENCOBOL"

Sergey's comment to this was:
OC will not work with stdcall and if stupid DB2 has only stdcall library 
than it might be only choice to create (take from DB2) some db2.h header 
file which will define those functions as stdcall, and simply add the 
inclusion of this header to the libcob.h
That should resolve the issue.
