I do not know if this is of some help, but here is how I link against
FLTK in my Win32 makefile (I could not get SCons to work with MinGW so
far, and I prefer to compile on Linux):

# this one is used for linking a program
	$(CXX) -O2 -o $@ $^ $(LDFLAGS) $(FLTK_LIBS) $(CSLIB_LNK) $(LIBS)
# and this one is for widgets.dll
	$(CXX) -O2 -shared -o $@ $^ $(LDFLAGS) $(FLTK_LIBS) $(LIBS)

where the variables are defined as follows:

CXX = wine D:/MinGW/bin/g++
CSLIB_LNK = -lcsound32    # or -lcsound64 if USE_DOUBLE
LDFLAGS = -L.
LIBS = D:/MinGW/bin/libsndfile-1.dll -lgdi32 -luser32 -lkernel32 -lm
FLTK_LIBS = -Wl,--enable-runtime-pseudo-reloc D:/MinGW/lib/fltk.dll -lstdc++
FLTK_LIBS += -lole32 -luuid -lwsock32

fltk.dll (version 1.1.7, compiled with --enable-threads) is included with
this package:
