[Coin-ipopt] Difficulities in installation on SunOS

[Andreas Waechter]

Hi Danh,

You were correct, the Makefile for the example did not automatically
include the -xlic_lib=sunperf flag if it was detected to work.

I corrected the configure script and submitted it to COIN.  It is already
available via CVS, and will be in tomorrow's tarball.

I will also send you the corrected configure script in a separate email.

Sorry for the hassle,

Andreas
