Would that be 2001-07-27?  Not all of us live in countries that flout ISO
standards!

That is a generated file.  It coems from m4/libtool.m4.

(! That looks like a bash bug.  Your bash version is ?  sh is supposed ot
have no line length limits.)

Do you have a current perl?  Globbing was changed in 5.6.0 to be handled
in C code, as I recall.  It does not happen on Solaris, Linux or Windows,
and I suspect a perl upgrade might fix it.  Try 5.6.1, if you are not
already using it.

(slower and less portable if it is not needed.)

Your perl version is ?
