Updated CYGWIN-ifort.mk

[arango]

Added additional constraints to the FC definition to allow blank spaces and parenthesis in the full compiler path:

# Use full path of compiler. Notice that a very special editing is
# done for the FC defintion to allow blank spaces and parenthesis in the
# compiler path. For example, we can have:
#
#      c:\\Software\\My Compilers (64 bit)
# or
#      /cygdrive/c/Program Files (x86)/Intel/Compiler/11.1/051/bin/ia32/ifort
# or
#      /cygdrive/c/Program Files/Intel/Compiler/11.1/051/bin/ia32/ifort
#
               FC := $(shell which ${FC} | sed 's|\([ |(|)]\)|\\\1|g')
               LD := $(FC)

Many thanks to David Robertson for fixing this problem.
