Spoke too soon: while I can step into the LCL directly, if I put a 
breakpoint in one of my packages (in a function which is called by the 
LCL, it implements a THelpManager), fpdebug doesn't stop at the breakpoint.
For it to work I have to add -gw3 to the "additions and overrides" (and, 
sorry to repeat myself, I didn't need to to that with gdb and -gl).
