     I am trying to install gromacs 4.5.3 on my desktop under Cygwin. Using 
the installation procedure from the Wiki:
Install fftw-3.2.2 with 
./configure --enable-sse --enable-float
make install

Then install gromacs with:
./configure --enable-shared LDFLAGS='-L/usr/local/lib'

The installation fails here with many errors not being able to find 
libraries associated with fftw tracing back to this error:

*** Warning: This system can not link to static lib archive 
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have.

The installation procedure from the Wiki works fine with gromacs-4.0.7. 
This error only occurs with the 4.5 series. Are there different default 
settings for where gromacs looks for fftw between 4.0.7 and 4.5.3? Any help 
would be appreciated.
