I did a try also.
With fresh untar the archive and replaced the acinclude.m4 with the new one.
for me bad luck with SuSE 9.2 and gcc version 3.3.4 (pre 3.3.5 20040809)

This afternoon i did install on a second box and did the patch on line194/195. 
With same suse version the ./reconf and ./reconf-all did not work. 
After a make distclean, I can't remember it did work or not, I restart again
with fresh untar and did the patch on line194/195. That is working now :)

Report with the updated acinclude.m4 from Laurent Carlier:
