Well, I know it's old, but I didn't notice in changelog that something
special new was added, so maybe this is somekind of bug?

Edit, tested with newer gcc and got new error:

db-checkpassword.c: In function 'sigchld_handler':
db-checkpassword.c:434:6: error: assignment of read-only member '__in'
db-checkpassword.c:437:26: error: assignment of read-only member '__in'
db-checkpassword.c:439:13: error: assignment of read-only member '__in'
db-checkpassword.c:440:26: error: assignment of read-only member '__in'
make[3]: *** [db-checkpassword.lo] Error 1


Seems this is quite old error -
