Thing `<<` is not defined

[lhutzelmann]

Hi,
I just started to use millfork, so I wanted to compile the fire.mfk example for C64. The following error occurred when compiling with "C:\dev\c64\millfork\millfork-0.3.26\millfork.exe" "c:\Users\lars_\Documents\C64\VSC_workspaces\test\fire.mfk" -o "c:\Users\lars_\Documents\C64\VSC_workspaces\test\fire.prg" -t c64
for release 0.3.26 (same for last few releases).

Any ideas what went wrong?

This has already been fixed together with #107.

I think I should make a new release as soon as possible. Thanks for the report.

The fix has been officially released in 0.3.28
