Package: autoconf
Version: 2.61-1
Severity: normal
Starting with 2.61-1 autoconf's AC_FUNC_FSEEKO no longer makes fseeko() or
ftello() visible on sid. It still worked with 2.60a4-1.
For instance:

./autogen && ./configure && make clean && make works fine on both i386
and amd64 when autoconf 2.60a4-1 is installed, but does not work when
autoconf 2.61-1 is on the system:

-MD -MP -MF ".deps/programm.Tpo" -c -o programm.o programm.c; \
| then mv -f ".deps/programm.Tpo" ".deps/programm.Po"; else rm -f
".deps/programm.Tpo"; exit 1; fi
| cc1: warnings being treated as errors
| programm.c: In function 'main':
| programm.c:8: warning: implicit declaration of function 'ftello'
| make[2]: *** [programm.o] Error 1
The produced config.h file does differ:

Both define HAVE_FSEEKO however:

c-261/config.h:#define HAVE_FSEEKO 1
stdio.h (libc6-dev 2.3.6.ds1-8) only makes fseeko()/ftello() visible if
_LARGEFILE_SOURCE (or __USE_LARGEFILE) is defined.
