Fixes between version 1.2 and version 1.2c

- Multiple pre/dat files option is fixed.

- Simulation bug is fixed.

- boundary problem in estimation of delta (e.g., dhat) for
  the linear model is fixed.

- Compiling now utilizes ./configure.


Fixes between version 1.0 and version 1.1.

- Phenotyped, but ungenotyped, founder couples having only one child
  are now handled correctly by the haplotyping algorithm (Thanks to
  Philip Stuart).

- Family specific information is now correct for all weighting
  schemes, not just the equal one.

- Haplotyping no longer causes problems when swapping to disk.

- X-linked scoring functions have been fixed.

- Numerical instability in information measure (when NPL score is very
  close to 0) has been fixed by employing the limit of the information
  measure that does not have the numerical problem arround NPL=0.

- Special thanks to Heather Cordell and Dan Weeks for bug catches.
