I'm getting the following warnings from aclocal 1.9.5 when it runs through wxGTK 2.4.2-r3:
/usr/share/aclocal/wxwin.m4:36: warning: underquoted definition of AM_OPTIONS_WXCONFIG
run info '(automake)Extending aclocal'
or see http://sources.redhat.com/automake/automake.html#Extending-aclocal
/usr/share/aclocal/wxwin.m4:59: warning: underquoted definition of AM_PATH_WXCONFIG
Created attachment 58563 [details, diff]
patch that fixes the warnings
Please, submit this upstream. Thanks.
