can't compile autoconf 2.62 or 2.63

Hey,

I'm trying to compile autoconf 2.62 or 2.63, unfortunately, there is an 
error when running make (i don't see any problem with configure):

Making all in m4sugar
make[3]: Entering directory `/home/vincent/tmp/autoconf-2.62/lib/m4sugar'
autom4te_perllibdir='../..'/lib AUTOM4TE_CFG='../../lib/autom4te.cfg' 
../../bin/autom4te -B '../..'/lib -B '../..'/lib                         \
         --language=m4sugar                      \
         --freeze                        \
         --output=m4sugar.m4f
autom4te: freezing produced output:
autom4te:
autom4te:
autom4te:

[snip a lot...]

autom4te:
make[3]: *** [m4sugar.m4f] Error 1
make[3]: Leaving directory `/home/vincent/tmp/autoconf-2.62/lib/m4sugar'


I have msys 1.0.11. Does someone know why there is such error ?

thank you

Vincent Torri
