- (unsigned)char explained
- The offical C language 'white book' discusses casts and coercions
- at length, but is not worded very precicely. In fact, there are
- two ways it might be interpreted; this ambiguity is mitigated by
- the fact that both ways produce the same result via different
- paths.
- Hans Spiller of Microsoft gave a paper at the last usenix
- discussing:
- 1) what the official standard is, with special DMR endorsement
- 2) how current (v7) compilers, both the 'pcc' and 'cc' products
- differ from this standard,
- 3) how 3.0 compilers follow the standard (almost exactly)
- 4) how to write code to attain portability across these various
- compilers.
- Copies are available upon request; perhaps I can get him to put a
- short summary on the net, if theres interest.
