For the linux case, 
I tested it with the latest test snapshot of www.rhide.com 
rhide 1.5 from 14 april 2002
with GDB 5.1.1

It works if you add these lines to rhide.env

RHIDE_FPC_FLAGS=$(C_FPC_LANG_FLAGS) $(LOCAL_OPT) $(addprefix -Fu,$(INCLUDE_DIRS)) $(addprefix -Fl,$(LIB_DIRS)) $(addprefix -Fo,$(OBJ_DIRS)) $(addprefix -Fu,$(SRC_DIRS)) $(C_EXTRA_FLAGS) -vR
RHIDE_COMPILE_LINK_FPC_AUTOMAKE=$(RHIDE_FPC) -o$(OUTFILE) $(SOURCE_NAME) $(RHIDE_FPC_FLAGS) -E-
RHIDE_LD_FPC=$(RHIDE_FPC) -E-

Note that these should be on only three lines,
each line beginning with RHIDE_???=
but might appear in more lines in your mail.

The two major problems where that -E option is
wrongly used in the default rhide environment variable
(-E+ means don't link now, but the reverse is assumed in rhide's default)

The obsolete -Up option is still used in default rhide environment version,
-Fu must now be used instead.

Nevertheless, I still think that Rhide is less appropriate than linux fp for debugging
because you can't set the terminal on which the debugge gets input and output
(while this can be set easily with the -T option for fp).

Do you run rhide on a console or under X?

For XP, the problem might be a bit more difficult to solve,
as I already explained in my previous answer.
