I believe I noticed similar issue when I was compiling gxine against
xine-lib-devel-1.1.9.1 but didn't paid much attention to it, as
xine-lib-devel-1.1.10 fixed it (on F-8).

I tried it with now again on F8 with xine-lib-devel-1.1.10, with
success. After upgrading to xine-lib-devel-1.1.10.1 this error pops out
(it's on F8 i386 with the F8 package from koji):

checking for XINE-LIB version >= 1.0.1...
*** 'xine-config --version' returned -1717986918.1072798105.-1717986918,

It's even stranger that the one in rawhide. The only change I did was
upgrade xine-lib* to 1.1.10.1-1.fc8... But I really don't understand,
where the numbers come from, since running xine-config --version by hand
returns 1.1.10.1.

Going through configure of gxine show possible root of the problem:

xine_config_major_version=`$XINE_CONFIG $xine_config_args --version | \
            sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\1/'`
     xine_config_minor_version=`$XINE_CONFIG $xine_config_args
--version | \
            sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\2/'`
     xine_config_sub_version=`$XINE_CONFIG $xine_config_args --version
| \
            sed 's/\([0-9]*\).\([0-9]*\).\([0-9]*\)/\3/'`

Looking at the output of xine-config --version | sed 's/\([0-9]*
\).\([0-9]*\).\([0-9]*\)/\1/' shows some buggy behaviour. The output is
1.1, as well as for 2, and for 3 I get 10.1. Looks like the sed
_expression_ is intended to work only with the MAJOR.MINOR.SUB version
string. If I add another .\([0-9]*\) to the _expression_ than the output
is correct.

Any idea how to workaround this so that it works both with x.y.z and
x.y.z.w like version strings?



Maybe counting the number of dots in  xine-config --version ?
