Only print the heading for the symbol table level if there is actually a
symbol on that level.
Ensure that no symbol with block level -1 is ever in the symbol table
(see rmsym).
Refactoring work in man.c r. 1.40 from twelve years ago introduced a
regression where input from the -m option was appended rather than
prepended to the search paths. Problem reported by C. Chapman on
netbsd-users.
The unit-tests for meta mode do not depend on filemon.
Adding nofilemon to .MAKE.MODE allows these to pass on
a system that would use filemon_dev but does not have
the module loaded.
Previously, the string literals "1" "2" "3" "4" were concatenated in the
order "23", "234", "1234". This influenced the location of the
diagnostics for traditional C (which doesn't know concatenation at all)
and for mixing regular strings and wide strings.
Now the diagnostics occur exactly where they are expected. The first
string literal defines whether the whole string is regular or wide, and
any further string literals must match it.
In traditional C mode, there are more diagnostics than before, but that
doesn't hurt since they are still correct and nobody uses lint in
traditional C mode anyway.
There is no need to make this variable externally visible. There are
several more variables in this file that could be unexported, leave
these for someone who knows whether vmstat.c is used by other parts of
the tree as well.
No functional change, OK mrg.
No functional change. As before, the string literals "1" "2" "3" are
not concatenated from left to right, instead concatenation starts with
"23" and then proceeds to "123".
Pre-C90 argument declarations have been old for more than 30 years now,
so mention that fact in the constant name. This reduces potential
confusion with other occurrences of the words 'arg' or 'argument'.
No functional change.
The commit that introduced the assertion failure looks innocent, it only
adds a few predefined functions for GCC mode. Nevertheless, before that
commit, lint consistently complained about 'error: void type illegal in
expression [109]', which doesn't make sense either.
This fix also removes the creative use of the initialization stack to
store the type of the statement expression. Having a separate stack for
these statement expressions makes the code easier to understand.
Filling deallocated memory with 0x00 may hide errors, so rather fill
with 0xA5.
While this doesn't change anything about the test about the assertion
failure after a do-while loop (see t_integration.sh, test case
assertion_failures), it may detect other similar bugs earlier.
The code to free the list node (as opposed to the node data) was
accidentally removed in lst.c 1.83 from 2020-10-23 as part of cleaning
up an unnecessarily complicated function for traversing linked lists.
The memory leak only affected a few lists that actually used Lst_Remove.
Most lists are append-only and are freed using Lst_Done or Lst_Free at
the end, which correctly free the memory.
