# This isn't an ordinary regression test, but instead it runs splint
# on the source files in the src directory. If the user doesn't have
# splint, we do nothing and pretend success.

# splint is very fussy, and prints many spurious errors, which cannot
# all be fixed by editing the dbacl source code. In particular,
# nonstandard header files cause a problem, as do compiler
# idiosyncracies. So it is not a good idea to run the lint check as
# part of the regular regression tests, since it would make dbacl
# uncompilable on some systems.

# There are other issues such as the fact that dbacl uses realloc and
# splint can't deal with this properly. But overall, it's worth using
# it.

# This part is messy. Some source files need special preprocessor symbols,
# so I've chosen to run a separate splint command on each source file. 
# Ideally, this would be generated automatically by analysing the automake
# file, but I have no idea how to do it. Note that splint should only 
# check the dbacl files, not the public domain files included from elsewhere.
