A quick look through suggest a cast could be reasonable in these case:

c:/mingw/msys/1.0/home/pgrunner/bf/root/HEAD/pgsql.3124/../pgsql/src/backend/port/win32/crashdump.c:
In function 'crashDumpHandler':

warning: format '%08x' expects type 'unsigned int', but argument 3 has
type 'DWORD'
pg_latch.c:147:4: warning: format '%d' expects type 'int', but argument
3 has type 'DWORD'

The remainder seem due to use of INT64FORMAT or other formats like %m
which gcc doesn't grok.

cheers
