Hi Bruno,
This grep expression has 99 dots. It should have 100 dots, no?
Evidently so. Any chance you could make up a test for it?
Probably something like filename-length-max=10 would be more
comprehensible. --thanks, karl.

error: the above filenames are too long

Some of these mentioned files have a length of 99 characters.
Why does the error complain not only about files that are *longer* than
99 characters, but also about files that are *exactly* 99 characters long?
The generated Makefile.in has
@if test -z "$(am__skip_length_check)" && find "$(distdir)" -type f -print | \
grep '^...................................................................................................' 1>&2; then \
echo 'error: the above filenames are too long' 1>&2; \
exit 1; \
else :; fi
This grep expression has 99 dots. It should have 100 dots, no?
