I have determined that if I change/hack the definition of MY_C_ISNAN to std::isnan i can get it to compile though that does assume I have

As of rev 877, I still see a similar problem. It looks to me like the problem is changes to BuildTools, which are incorporated in CoinUtils 1.0.4 but not in Clp 1.3.3 or DyLP 1.1.0. If I configure with --enable-doscompile, all is copacetic. Without --enable-doscompile, there are lots of interesting warnings during configuration, followed by (in my case) compilation failure in clp. The problem is that -mno-cygwin is mandatory in the Clp and DyLP releases, but the CoinUtils release incorporates the version of BuildTools (with --enable-doscompile) that makes it optional. Values stored in config.cache during CoinUtils configuration without -mno-cygwin are thus inappropriate during Clp and DyLP configuration with -mno-cygwin. The correct fix is for the Clp and DyLP project maintainers to generate updated releases.

Use DyLP release 1.1.1, it's up-to-date with respect to BuildTools 0.5.3.

This really should be fixed as of BuildTools/0.5.4. I'm going to declare victory.
