Follow-up Comment #1, bug #45345 (project screen):
The relevant code (replacing getlogin()) is behind a BUGGYGETLOGIN. Is
this macro nowadays still relevant? acconfig.h says about this macro:
/*
* If ttyslot() breaks getlogin() by returning indexes to utmp entries
* of type DEAD_PROCESS, then our getlogin() replacement should be
* selected by defining BUGGYGETLOGIN.
*/
In contrast, we have in configure.in:
oldlibs="$LIBS"
LIBS="$LIBS -lelf"
AC_CHECKING(SVR4)
AC_TRY_LINK([#include <utmpx.h>
],,
[AC_CHECK_HEADER(dwarf.h, AC_DEFINE(SVR4) AC_DEFINE(BUGGYGETLOGIN),
[AC_CHECK_HEADER(elf.h, AC_DEFINE(SVR4) AC_DEFINE(BUGGYGETLOGIN))])]
,LIBS="$oldlibs")
So whether getlogin() will be replaced depends on whether libelf is
installed...
