What version of the FAQ do you have?  The latest one (available as 
faq102.zip from the same place you get DJGPP) explaines the reasons and 
the ways to deal with them in section 10.10:

10.10 Q: When I try to recompile the LIBGRX graphics library, I get error
         messages from Make saying ``missing separator''.  But I didn't
         even touch those Makefiles, so what gives??
      A: LIBGRX was developed with Borland version of Make, so it uses
         features specific to that program.  The reason for this is that
         with DJGPP Make, you cannot reliably run 2-3 levels of nested
         Makes.  Therefore, to compile LIBGRX you have to use Borland's
         Make or else convert all the Makefiles to GNU Make syntax.  If
         you use one of the Borland's products, be sure not to use one of
         those which run in protected mode (like the one supplied with
         Borland C++), because it's incompatible with DJGPP (see Section
         6.14 above); use Make from any Turbo compiler instead.  If you
         want to convert to GNU Make, then here is a list of major
         differences:

           * Borland Make doesn't insist that commands in the rules start
             with a TAB (it can be blanks); GNU Make barfs on command
             lines which start with blanks.

           * The syntax for conditional directives is different:

             Borland syntax            GNU syntax
             -------------------------------------------------------
             !include "file"           include file
             !else                     else
             !endif                    endif
             !undef symbol               -
             !error "string"             -
             !if expression              - (use ifeq/ifneq or ifdef)
             !if $d(symbol)            ifdef symbol
             !if !$d(symbol)           ifndef symbol
             !elif                       - (use else and ifeq/ifneq)

OTOH, why do you need to recompile at all, libgrx comes with a 
precompiled library file which you only have to link with your programs.
