DDD for Mac OS X

New features and minor improvements

• Support for PHP debugger has been added (1). This is essentially not tested.
• Source files in subdirectories should be located automatically when using dbx (tested on Solaris' dbx) (2).
• The perl version supported by DDD is now 5.8.x. The perl debugger changed between perl 5.6.x and perl 5.8.0, which made this update necessary. This change is not backwards-compatible. If it is not possible to upgrade your perl version to 5.8.x or newer, then you can simply install the file "perl5db.pl" from a recent perl distribution into your old perl tree.
• Through the maintenance menu ("ddd --maintenance"), it now possible to get a leak check of ddd if ddd is run under valgrind. This is only useful for ddd developers (or anybody that wants to help making ddd better).
• Several minor bugs fixed, some memory leaks plugged, more code clean-up done.
• A bug affecting platforms where the size of function pointers is 16 has been fixed.
• The settings window now starts at a larger, more reasonable size, and allows the user to resize it.

• The configure machinery has been updated to conform more closely to the autoconf 2.5x requirements. Several bugs have been fixed.
• libiberty (which provides missing standard functions) is not linked by default anymore. configure has a new option '--with-libiberty' that enables the libiberty support if required. If nobody complains, libiberty will be unbundled in a next version.
• The libiberty distributed with ddd has been upgraded to the one included in GCC 3.4 20040116. It fixes some configuration problems.
• Builds with GCC 3.4, with IBM xlC on AIX, with Compaq/HP cxx on Tru64, on X11R5 based systems, with SGI CC on IRIX should be OK.
• Builds on HP-UX should now work out-of-the-box. Motif is linked statically and the Athena libraries are now found by default.
• Builds without Motif/Lesstif available abort with an adequate message.
• Builds with readline support now work. readline is not bundled anymore.
• Builds without -DNDEBUG (i.e. with "assert" enabled) now work. Default build enables assertions (i.e. -DNDEBUG is not used).
• Several missing files in the distribution are now included.
• Cygwin is supported again.
