Patch for quoted string in configure.in in CheckIPod

Subversion revision 4707.
I tried the alternative of adding an extra pair of quotes and obtained:

AC_HELP_STRING([--enable-ipod], [configure SDL to work with iPodLinux [[default=yes on arm-elf]]]),
        , enable_ipod=yes)

produces in configure after autogen.sh:

  --enable-ipod           configure SDL to work with iPodLinux
                          [default=yes], [                          ], [79])[][]_m4_text_wrap_word([on], [                          ], [79])[][]_m4_text_wrap_word([arm-elf]
Comment 2 davshaonr 2009-09-10 08:39:47 UTC 
For subversion revision 4707 of libsdl 1.3, I believe the problem also applies to Mac OS X 10.6 (Snow Leopard) using macports, with

$ autoconf --version
autoconf (GNU Autoconf) 2.64

$ gm4 --version
m4 (GNU M4) 1.4.13

The problem appears to be with the line in configure.in:

AC_HELP_STRING([--enable-ipod], [configure SDL to work with iPodLinux [default=yes on arm-elf]]),

I attempted to add a pair of extra quotes.

AC_HELP_STRING([--enable-ipod], [configure SDL to work with iPodLinux [[default=yes on arm-elf]]]),
        , enable_ipod=yes)

which produces in configure after autogen.sh:

  --enable-ipod           configure SDL to work with iPodLinux
                          [default=yes], [                          ], [79])[][]_m4_text_wrap_word([on], [                          ], [79])[][]_m4_text_wrap_word([arm-elf]

This is fixed in subversion, thanks!
