| I've been working on getting freeciv to compile in 
windows, but cygwin's autoheader(version 2.57) gives this error:   ' is already registered with 
AC_CONFIG_FILES. autoconf/status.m4:844: AC_CONFIG_FILES is expanded 
from... configure.ac:715: the top level autom4te: /usr/bin/m4 failed with exit status: 
1 autoheader: /usr/autotool/devel/bin/autom4te failed 
with exit status: 1   Does anyone have any clue what this means?  
I've tried the stable version of autoconf, but goes insane(even more so) while 
building makefiles. |
