1aab287189 Fixed the handling of "while (0) {}". 
It's a corner case; but, conditional macroes might create it -- better safe than sorry.

be772c0198 Bumped version. 
As suggested the incompatibility resulting from 02daf9f8b5 makes a new version appropriate.

dce5783dc9 Fixed the simulations of the stack pointer and the "break" and decimal-mode flags. 
* The pointer wraps around the stack page.
* The break flag exists on only the stack, and only after an interrupt.
* 65C02 interrupts clear the decimal-mode flag.

02daf9f8b5 So far the built-in inlining of several known standard function was always (!) enabled and the option -Os enabled additional, potentially unsafe inlining of some of those functions. 
There were two aspects of this behavior that were considered undesirable:
- Although the safe inlining is in general desirable it should only be enabled if asked for it - like any other optimization.
- The option name -Os implies that it is a safe option, the potentially unsafe inlining should have a more explicit name.

So now:
- The option -Os enables the safe inlining.
- The new option --eagerly-inline-funcs enables the potentially unsafe inlining (including the safe inlining).

Additionally was added:
- The option --inline-stdfuncs that does like -Os enable the safe inlining but doesn't enable optimizations.
- The pragma inline-stdfuncs that works identical to --inline-stdfuncs.
- The pragma allow-eager-inline that enables the potentially unsafe inlining but doesn't include the safe inlining. That means that by itself it only marks code as safe for potentially unsafe inlining but doesn't actually enable any inlining.

e4aee2ba34 cc65: remove un-needed logic from octal parsing

6ee1fd2a67 scanner: Correct handling of \0101 
The C language has this oddity that octal constants are 3 bytes so the sequence
"\0101" is two bytes and well defined by the langage. cc65 currently misparses
this as a 1 byte octal code. Add a count to fix this.

a6eb7d0763 Fixed how ca65 handles some debug info from cc65. 
ca65 used to claim that an assembler error/warning was found on a C code line; and, that an Assembly line is only indirectly related to it.
Now, ca65 says that the Assembly line has the problem; and, that the Assembly line was produced from the C line.

8dd003d2b3 Added --print-target-path option. 
If cc65 is installed and used as designed there's no need whatsoever for CC65_HOME (both on *IX and Windows) from the perspective of the cc65 binaries. If the user however has to access files from the 'target' directory thenhe ends up with some assumption on the cc65 installation path nevertheless :-(

In order to avoid this I added the --print-target-path option. It "exports" the logic used by the cc65 binaries to locate their files to the user thus allowing him to leverage the same logic to locate the target files in his build scripts / Makefiles.

8d5717b57a Small optimization of some cc65-generated loops. 
"bne" means also branch-on-not-zero.  Therefore, this optimization doesn't put a compare-to-zero between an increment and a "bne".

2c7ccca210 Added the optional C keyword "volatile" to the __asm__ statement grammar. 
It prevents the statement's Assembly code from being optimized (e.g., moved or removed).  Optimization is disabled for that statement's entire function (other functions aren't affected).
