negative.

In particular, comparing signed and unsigned integers, and doing

present, can be dangerous and lead to unexpected results.

So fix the resulting warnings (which are due to -Wsign-compare which

cleanup: turn off some unused flex options

We do not use yyunput or yyinput.  Turning them off slightly improves
the scanner performance (not that that's important) but also prevents
"defined but not used" compiler warnings.

12 years agocleanup: move declarations of external objects into header files
Ian Jackson [Mon, 16 May 2011 10:13:59 +0000 (11:13 +0100)]
cleanup: move declarations of external objects into header files

It is not a good idea to declare external objects in .c files.  Every
external object (ie, object with external linkage) should be declared
exactly once in a .h file, and every .c file that refers to it or
defines it should #include that header.

When combined with appropriate compiler warnings, this ensures that
every file sees the same signature for every such object.  (At least
for functions.)
