The following bug has been logged online:

Bug reference: 4210
Logged by: Andrew SG Rojek
Email address: developer.admin@ntlworld.com
PostgreSQL version: 8.3.1
Operating system: OSX 10.5.2
Description: signedness of pointer targets
Details:

Whilst making psqlodbc-08.03.0200, make reported a large number of warnings
relating to the signedness of pointers:

pointer targets in assignment differ in signedness
pointer targets in passing argument 2 of ... differ in signedness
...

for a number of files.

Is this something to be concerned about or will ODBC function reliably?
