# Installing many files should not exceed the command line length limit.

# Here, the main issue is that we may prepend `$(srcdir)/' to each file,
|
|
# which may cause much longer command lines. The list of files must
|
|
# anyway remain below the limit, otherwise `make' won't be able to even
|
|
# fork the command.
|
|
#
|
|
# Further, the install rule should honor failures of the install program.
|
