5c43d1e04f Changed codegen for postfix inc/dec operations by deferring them till sequence points. 
This usually allows faster & smaller code.
Note that deferred operations must still be called at sequence points even if the whole expressions containing them had constant values.

3df6c383c0 Add support for static_assert 
Add C11's _Static_assert and static_assert macro.

This is like #error, but is handled at a later stage
of translation, so it is possible to check sizes of
types, values of enums, etc.

a0db846a97 Allowed old-style (K and R) function declarations to be fastcall. 
That lets them match old-style definitions.  It avoids "Type conflict" error messages.  It allows shorter function calls.

Fixed the types of some variables in "test/ref/otccex.c".  It avoids crashes on 64-bit Windows (32-bit Windows with 64-bit pointers).

644d623d31 Reset the name of the "current bss segment" before writing bss variables into the output Assembly file. 
Then, cc65 can notice a single "#pragma bss-name()" at the beginning of the variables list.

a6b04f6e97 Changed most "backticks" (grave accents) into apostrophes. 
Quotations that are embraced by tick marks now look better, in most fonts.

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.
