Dependency scanner include path

[Zachary Deretsky]

Only files in the local directory are checked, not on the include path.

What am I doing wrong? I use cons 2.1.2.

Here is my scanner:

-------------------------------------
sub cons::iScan {
    my(@includes);
    do {
        if(/^%(include|import|extern)\s+(\w+\.)(i|ii|iic|iim|hpp)\s*$/) {
            push (@includes, "$2$3");
        };
    }
    while <SCAN> ;
    if(scalar(@includes)) {
        print "INCLUDES:   ", join(' ', @includes), "\n";
    };
    close(SCAN);
    @includes
    };
----------------------------------------

Here is the relevant part of Conscript:

-------------------------------------------
$swigPath = $CONS->{ENV}{SWIG_LIB} . "$absInclude;";
print "SWIG PATH: $swigPath\n";
$CONS->QuickScan(\&cons::iScan, "rings.i", $swigPath);
-------------------------------------------

If I change a file in the local directory (ctm.ii, rtc.ii, rings.ii,
rings.iim)  then rebuild happens.
If I change a file elsewhere on the SWIG PATH (rngCommon.hpp) , then nothing
happens.
Can it be a problem with colon versus semicolon as path separator?
How can I use colon on NT with paths with drive letters?

Here the output for the second case:

-----------------------------------------------

I will appreciate guidance here. Zach
