How to compile Fortran 90 subroutine under CYGWIN

Dear all,
I am using Windows XP and have installed cygwin, in which the g++ C++ compiler are installed. I have programs written in c, Fortran 77 and Fortran 90. Now, I am trying to build in cygwin. When I type ‘make all’ in cygwin. The error message is
gcc –c runslhg.f
gcc –c intrface.f
make: *** No rule to make target ‘Testfor90.o’, needed by ‘sloshDos’. Stop
Both runslhg.f and intrface.f are written in Fortran 77. Testfor90.f90 is written in Fortran 90.Does that mean I could build fortran 90 in cygwin? I would appreciate if someone give me a hint what should I look at. Thank you.

Here is the code of ‘makefile’

#!/bin/make
SHELL = /bin/sh
CC = gcc
F77 = g77
STRIP = strip
STD_FLAGS = -O3 -Wall -pedantic -ansi

STD_DEF = -D_WINDOWS_ -D_GCC_
STD_INC = -I.
STD_LIB = -lg2c -L/usr/lib -lm
PRJ_NAME = sloshDos
TARGETS = $(PRJ_NAME)
CFLAGS = $(STD_FLAGS) $(STD_DEF) $(STD_INC)
