This removes all the various workarounds for avoiding compiler warnings with Flex 2.5.35. Several recent patches have added additional warnings that would either need to be fixed along the lines of the existing workarounds, or we decide to no longer care about this, which we do here. Flex 2.5.35 is extremely outdated, and you can't even download it anymore from any of the Flex project sites, so it's nearly impossible to support. After this, using Flex 2.5.35 will still work, but the generated code will produce numerous compiler warnings.

# There is no correct way to write a rule that generates two files.
|
|
# Rules with two targets don't have that meaning, they are merely
|
|
# shorthand for two otherwise separate rules. If we have an action
|
|
# that in fact generates two or more files, we must choose one of them
|
|
# as primary and show it as the action's output, then make all of the
|
|
# other output files dependent on the primary, like this. Furthermore,
|
|
# the "touch" action is essential, because it ensures that gram.h is
|
|
# marked as newer than (or at least no older than) gram.c. Without that,
|
|
# make is likely to try to rebuild gram.h in subsequent runs, which causes
|
|
# failures in VPATH builds from tarballs.
