 I recently compiled the new gcc-4.3.1 on my Gentoo system. Now the MythTV
 configure does not work anymore:

 {{{
 ./configure: line 2885: test: /var/tmp/portage/sys-devel/gcc-4: integer
 expression expected
 }}}

 I added some debugging statements that show the following:

 {{{
  gcc-version: /var/tmp/portage/sys-
 devel/gcc-4.3.1-r1/work/gcc-4.3.1/configure
 4.3.1
  GCC_MAJOR: /var/tmp/portage/sys-devel/gcc-4
  GCC_MINOR: 3
 }}}

 running "gcc -v 2>&1 | grep version | cut -s -d' ' -f 3" returns the
 following result:
 {{{
 /var/tmp/portage/sys-devel/gcc-4.3.1-r1/work/gcc-4.3.1/configure
 4.3.1
 }}}

 running "gcc -v":
 {{{

 }}}

 I made the following adjustment to the script:

 {{{

 +gcc_version=$($cc -v 2>&1 | grep "gcc version" | cut -s -d' ' -f 3)
  GCC_MAJOR=$(echo ${gcc_version} | cut -s -d'.' -f1)
  GCC_MINOR=$(echo ${gcc_version} | cut -s -d'.' -f2)
 }}}

 Is this a problem with my setup? If so, I will try to fix it here. If not,
 is this a workable solution, since I am not sure if this always works
 correctly, but it works for me.

 Hopefully this helps.
