xa 2.3.14, the 6502/65816 cross-assembler

xa (xa65) 2.3, the current minor release of this long-lived 6502 and 65816 cross-assembler, gets one more stay of execution to 2.3.14 in order to fix a segfault for recursive macros with smaller arities and a regression from 2.3.13 with nested comments (though André and I may consider whether we will still support this in 2.4). The testsuite is naturally expanded and tuned up a little bit, too, and as always run to completion on the multiple current and geriatric systems here at Floodgap. I know I'm sounding like a broken record but 2.4 is coming and we will be breaking some edge-case compatibility and cutting out some long-deprecated corners of the code, so it was important to ensure 2.3.x was tuned up as much as possible before putting it out to pasture. There is no corresponding new release for dxa, the companion disassembler; work is still being done there.

The new release and archived old versions are updated on xa's home page. Both xa and dxa are available under the GNU Public License v2.
