Don't forget about LCC; the new freely available, retargetable C compiler
produced by Princeton/Bell-Labs.


The total amount of code in LCC is perhaps an order of magnitude less than
that currently present in the GCC distributions. For someone who just
needs a *comprehensible* C front-end (for some small project) I think LCC
is the new compiler of choice. (And by the way, my own testing indicates
that the latest version of LCC is also more fully conformant to the ANSI C
standard than GCC is... even when using GCC's -pedantic-errors option. I
know of several `standard conformance' front-end bugs in GCC. Currently,
I don't think I know of _any_ front-end bugs in the latest LCC release.
Of course, that doesn't mean there aren't any. I just means that they are
well hidden. :-) --
