Giving up

[Rumbu]

Hi,

Sincerely I am tired to maintain my library with every change 
made by D compiler. Mostly regressions. Bug reports are ignored 
or challenged, I don't have time to argue.

Therefore, if someone finds interesting my decimal lib [0], 
please continue or maintain it from here, I stopped completely to 
adjust it. It is still working, but unit tests are not running 
anymore because of regressions in compiler.

The last issues are generated by unpublished changes in the 
parser:

Examples:

```
float z = 85886696878585969769557975866955695.E0; //integer 
overflow, I don't see any int
real x = 0x1p-16383; //number `0x1p-16383` is not representable. 
It is, trust me.

```

Please don't ask me what is the last version when everything 
worked like a charm. I don't know and now I don't care.
