Your problem is that gcc-2.95 uses source language extensions that are
no-longer supported by more recent versions of GCC.

You have three options
1) Build a more recent version of gcc for ARM (2.95 is *very* old now
and hasn't been supported for more than 5 years).
2) Use an older native compiler (gcc-3.4 or older)
3) Try to back-port the various source code changes needed to make 2.95
work with a more recent compiler.
