Dear all,
I am using Windows XP and have installed cygwin, in which the g++ C++ compi=
ler are installed. I have programs written in c, Fortran 77 and Fortran 90.=
 Now, I am trying to build in cygwin. When I type =91make all=92 in cygwin.=
 The error message is
gcc =96c runslhg.f
gcc =96c intrface.f
make: *** No rule to make target =91Testfor90.o=92, needed by =91sloshDos=
=92. Stop
Both runslhg.f and intrface.f are written in Fortran 77. Testfor90.f90 is w=
ritten in Fortran 90.Does that mean I could build fortran 90 in cygwin? I w=
ould appreciate if someone give me a hint what should I look at. Thank you.

Here is the code of =91makefile=92
