I have some new information. If I add the attached patch to snprintf.c,
I should see see snprintf() being called printing "0", vsnprintf()
printing "1" and dopr(), "2". However, I only see "0" printing in the
server logs.
I think this means it is finding our /port/snprintf(), but when it calls
vsnprintf, it must be using some other version, probably the operating
system version that doesn't support %lld.
I am also attaching the 'nm' output from libpgport_srv.a which does show
vsnprintf as being defined.
Win32 doesn't like multiply defined symbols so we use
-Wl,--allow-multiple-definition to allow multiple symbols.
I bet if I define LONG_LONG_INT_FORMAT as '%I64d' it would pass the
regression tests. (I will test now.) Our config/c-library.m4 file
confirms that format for MinGW:
# MinGW uses '%I64d', though gcc throws an warning with -Wall,
The big question is why our own vsnprintf() is not being called from
snprintf() in our port file.
