rgbds-0.4.2-win64 - compile error

[sttng]

I get several errors with rgbds-0.4.2 (or specific rgbasm) such as

ERROR: video.asm(117):
    syntax error
error: Assembly aborted (1 errors)!

or

ERROR: video.asm(446):
    syntax error
error: Assembly aborted (1 errors)!

These lines seem to be related to calculation including defined constant symbols, ie.

117: jp $ff00 + compression_jr
...
446: ld hl, $ff00 + current_line

Seems rgbds-0.4.2 doesn't like calculation with symbols.
