>Description:
When linking a program against libdb2, from the Berkley DB v2 package,
calls to getpwuid(2) and getpwnam(2) fail on EINVAL.  Note that you 
don't actually have to invoke any of the DB functions...merely linking
against the library is enough to cause a failure.

This problem *may* be related to PR bin/21659.

getpw* work if you link against BDB v3 or v4.
>How-To-Repeat:
Compile this program and link with -ldb2:

#include <sys/types.h>
#include <unistd.h>
#include <pwd.h>
#include <stdio.h>
#include <db2/db.h>

int main (int argc, char **argv)
{
        struct passwd *pw;

        pw= getpwuid(getuid());
        if ( pw == NULL ) {
                perror("getpwuid");
                return 1;
        }
        printf("name= %s\n", pw->pw_name);
}
