+ missing sigwait prototype on BSD/OS 4.0/4.0.1
+ PTHREAD_ONCE_INIT unbraced initializer warnings on Solaris 2.8.
+ IN6ADDR_ANY_INIT unbraced initializer warnings on BSD/OS 4.*, Linux and
Solaris 2.8.
Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const. Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.
The macro DE_CONST was added to isc/util.h to deal with a handful of very
special places where something is qualified as const but really needs to have
its const qualifier removed.
Also cleaned up a few places where variable names clashed with reserved
identifiers. (Which mostly works fine, but strictly speaking is undefined
by the standard.)
Minor other ISC style cleanups.
public functions did not have an isc__ prefix, and
referred to functions that had previously been
renamed.
184. [cleanup] Variables/functions which began with two leading
underscores were made to conform to the ANSI/ISO
function declaration and comment reformatting in accordance with coding
style document.
check_overrun conditionally compiled based on ISC_MEM_FILL and
ISC_MEM_CHECKOVERRUN to avoid compiler warnings about being defined
but not used if one of those two CPP symbols is not defined.
isc_file_fseek(), isc_file_fread(), isc_file_fwrite(),
isc_file_fflush(), isc_file_ffsync(), isc_file_remove()
to encapsulate nonportable usage of errno and fflush().
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
