Using the older RTLs doesn't work for C since the problem is what the headers defined.

You need to use /DEFINE=(__CRTL_VER=80400000) when you compile the code [or whatever the oldest version you want to support].
Those symbols are described in the CRTL reference manual.

The new fpclassify() work is guarded such that older __CRTL_VER will skip the definition of the new support
and the references to the new MATH$ entry points.  The release notes for another RTL ECO kit will be clearer.

And yes, putting new functionality in remedial ECO kits is not something that has been done in the past.
