make bug on cygwin

[jcwarner]

A few months ago, a correction was made in the makefile to correctly use

source-to-object = $(call source-dir-to-binary-dir,   \
                   $(subst .F,.o,$1))

The word 'binary' was misspelled, and is now correct. However, that fix has created a problem. I can not correclty build on Cygwin. Cygwin now creates *.obj files. The Cygwin-ifort.mk file has a catch to force ifort to make *.o not *.obj using

%.o: %.f90
	cd $(SCRATCH_DIR); $(FC) -c $(FFLAGS) $(notdir $<) /object:$(notdir $@)

However, this line is not invoked anymore. I traced it back to the makefile, and was able to get it to build correctly by modifying line 278-279 from

  $1: $2 $3
	cd $$(SCRATCH_DIR); $$(FC) -c $$(FFLAGS) $(notdir $2)

to

  $1: $2 $3
	cd $$(SCRATCH_DIR); $$(FC) -c $$(FFLAGS) $(notdir $2) /object:$(notdir $1)

Yes, thank you. I also modified the definition of MAKE_MACROS to

MAKE_MACROS := $(shell echo ${HOME} | sed 's| |\\ |g')/make_macros.mk

so the file make_macros.mk is created temporarily in the user's home directory and then moved to the project directory. Previously, this file was created in the Compilers directory. This was problematic because other users in a computer system were not allowed to use a ROMS source code own by another user due to the lack of writing privileges to the Compilers directory.

The change in the makefile is reversed due to the fact that not all the compilers accept the option flag /object. However, this rule is now stipulated in CYGWIN-ifort.mk to override this rule to use .o instead .obj. This a more targeted way to override such a rule.
