0ab2a4fa16 Add consistency checking for symbol flags 
while also adding some consistency.
All listings now list . (dot) as defined so they need updating.

22fdaedded Some floating point fixes. 
- Fixed immediate source operand of LDEXP, LD[IL][FD]
  which is an integer, unlike several other FPP instructions.
- Renamed floating point instruction formats so they match the
  instruction descriptions in the architecture handbook better.

1d799534bb Add Commercial Instruction Set. 
I haven't done much compatibility testing with MACRO11 to check
weirdnesses, but the original functionality is very limied: none
of the mnemonics has operands.

c587587f49 Fix/work around a bug in parse_expr(). 
There was an obscure bug in parse_expr(), used to evaluate 'if df',
where it could skip past the end of the line marker.

If this happened inside an expanded macro, then after that was the
next line...
In other cases it might be worse.

Now that this is fixed, another check for line end junk can be enabled.

0e3d596daf Allow implicit floating point immediate for FPP instructions 
which have an general (source) argument and an AC destination.
There are no FPP instrs which have 1 general source arg;
only with 1 general destination (even TSTF).

The -I option is used to specify the search path for .INCLUDE files.
It also appends this to the "INCLUDE" environment variable.

d38f4009c4 Crank up the warning levels, and adjust the code to silence ... 
several compilers:
- gcc version 4.5.3 (NetBSD nb2 20110806)
- gcc version 4.9.2 (Ubuntu 4.9.2-10ubuntu13)
- Ubuntu clang version 3.6.0-2ubuntu1 (tags/RELEASE_360/final) (based on LLVM 3.6.0)

The warnings were mostly about local variables shadowing others,
unused function parameters, and C++ style comments. Some variables were
indeed used before set.

Note that on Linux, using -std=c99 does stupid things like *remove* the
declaration of strdup() from <string.h>. Therefore I've reluctantly used
-std=gnu99.
