Pre-Announcement for R.S.N.

5.9

#include behavior cleaned up

It assumed that relative paths were only relative to current dir. Relative paths will now also search through the "-L" directory list. Additionally, names starting with "$@" will be searched for in the pkgdatadir.

another sizeof(int) != sizeof(size_t) issue

Introduced in the fixes for this that went in for 5.8.8.

Announcement for January 27, 2007

5.8.9

Parallel make does not work

Don't do that. There are intermodule dependencies. The infrastructure should be redone as a single level make. Not today. “.NOTPARALLEL:” has been added to all but the test Makefile.ams.

conflicting greps

Occasionally, some folks wind up using a “egrep” to “grep -E” wrapper that invokes a grep program that does not grok the “-E” option. GREP, EGREP and FGREP are now all configured strings.

config files and hierarchical option arguments

It was buggy. I am sure nobody has been using it. It works now. I'm using it now.

5.8.8

This is a nitpick release (unless a nit affects you):

config tests

POSIX rules for handling return values from setjmp were not scrupulously followed in the config test. That breaks on Cygwin.

setjmp usage

POSIX disallows capturing the return value from setjmp(). Fixed.

Optimizers coelesce constant strings

so testing for different addresses won't necessarily work.

some code presumed sizeof(int) == sizeof(size_t)

The presumption was subtle.

stress testing

Mishandled pointer after allocation failure

5.8.5

ag-fprintf

This function will allow you to format and emit text into a suspended output stream. If the first argument is an integer, then the output stream that many entries back into the output stack will be used (see out-push-new and out-pop). If the first argument is a string, it must name a suspended output stream (see out-suspend and out-resume).

string tables

Sometimes, it is really handy to be able to stuff strings into a const character array and know the byte offset to the start of that string. For example, it took a few minutes to produce this from the string, "that was the week that was":

static const char scribble[18] =
    "that\0" "was\0"  "the\0"  "week\0";

#define STRING_CT 6

const char *ap[7] = {
    scribble + 0,
    scribble + 5,
    scribble + 9,
    scribble + 13,
    scribble + 0,
    scribble + 5,
    NULL };

notice that duplicates have been removed.
