His error is caused by the fact that the system is recognized by configure
as "next/" without my patch; I have found out that if it was recognized as
"next/5" then --with-next framework will compile almost correctly, and will
take care of the __eprintf and _environ symbols
I never got errors on the "restFP" and "saveFP" symbols.
I addressed it by making the system recognizable as something sane, and
using the same LIBTOOL_CRUFT and LDSHARED as next/5
When I get back to my Mac I can get some more details for you...
essentially _environ should be left undefined (via ld's -U option),
___eprintf is found using -lcc_dynamic

Let me add some stuff to make --with-next-framework build correctly as well.

HFS+ is case-preserving. As long as fcntlmodule.so can't be imported
*again* as FCNTLmodule.so, thereby causing a crash! The check_case stuff
uses the Win32 api, but something like that will be necessary!
