Comment:

 With r144808 xkbcomp does not compile on Mac OS X 10.5 anymore (probably
 also 10.4, maybe also later versions of OS X).

 In the config.log (attachment:config-leopard-ppc7450.log) it says:
 {{{
 configure:3212: checking whether the C compiler works
 configure:3234: ccache /usr/bin/gcc-4.2 -pipe -Os -Wno-string-compare

 cc1: error: unrecognized command line option "-Wno-string-compare"
 configure:3238: $? = 1
 configure:3276: result: no
 }}}

 If I remove the lines added by r144808 from my Portfile I can upgrade
 successfully.

 Would it be possible to only add -Wno-string-compare if needed by the
 compiler?
