Hello. I see that binutils, GCC and GDB still use the Automake's 'cygnus' option in some of their makefiles:
$ grep_cygnus() { > grep -r 'cygnus' . \ > | perl -ne '/(^|[^@])cygnus($|(:!\.com\b))/ and print' \ > | grep -v '^[^:]*/Makefile\.in:'; \ > } $ (cd ~/src/binutils && grep_cygnus) # BINUTILS ./bfd/doc/Makefile.am:AUTOMAKE_OPTIONS = 1.9 cygnus ./binutils/doc/Makefile.am:AUTOMAKE_OPTIONS = cygnus ./etc/configure.texi:AUTOMAKE_OPTIONS = cygnus ./gas/doc/Makefile.am:AUTOMAKE_OPTIONS = 1.8 cygnus $ (cd ~/src/gdb && grep_cygnus) # GDB ./bfd/doc/Makefile.am:AUTOMAKE_OPTIONS = 1.9 cygnus ./etc/configure.info: AUTOMAKE_OPTIONS = cygnus ./etc/configure.texi:AUTOMAKE_OPTIONS = cygnus $ (cd ~/src/gcc && grep_cygnus) # GCC ./zlib/Makefile.am:AUTOMAKE_OPTIONS = 1.8 cygnus But this option is going to be deprecated in Automake 1.12.1 and removed in Automake 1.13: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11034> I just wanted to give you this head-up so that you won't be unpleasantly surprised by the change. Note that the actual removal of the 'cygnus' option won't take place until Automake 1.13, which will at best be released five or six months from now (and probably later than that). Best regards, Stefano
