Correction: libtool 2.4.4 failed test demo-exec: helldl crashed

I mistakenly reported an error message which didn't occur in this case. 
The "Error 53" was when building gettext (on other tests besides those 
which it's rpath.README says are "known to fail"), presumably because 
current my version of libtool is too old. make check didn't give me an 
error code, but the WinXP "select a debugger" window appeared (but 
unfortunately had only an expired trial of MS Virtual Studio Pro's 
debugger to offer -- no help from it).
