Yes but that could also be because of "GCC 4 ABI changes that require apps to
be recompiled":http://dev.haiku-os.org/wiki/R1/ImprovementsSinceAlpha1

Not sure because I still think gcc4 stuff should work if compiled on gcc4
system and transfer over the gcc4 libraries and programs to gcc2 system. The
gcc4 libraries (& program) would be identical on both systems so if any
breakage happened it would have to be with the kernel (or linking to gcc4
server)? Maybe another dev can give more info here.
I think main issue is that people install gcc4 libraries in gcc2 folders and
also the ABI change that happened breaking many gcc4 programs. Most gcc4
programs still have not been updated on Haikuware and could be affected (ie,
broken).

That is fine but that still does not solve any ABI changes that break gcc4 apps
later on. See my first reply. And people use a zip file to install gcc4
libraries which means gcc4 libs will end up in /boot/common/lib (which is gcc2
lib folder on gcc2 system). That is why I brought up BASH script to do gcc4
library install on gcc2 release for non-experts.
