Try to add the following line to config/s.h after running configure:

#define USE_MMAP_INSTEAD_OF_MALLOC

If it works, I'll update the configure script accordingly.

Also, what does "configure" report as the system type? The first line,
"Configuring for a xxx-yyy-zzz ..."

It is better now but it fails on assembler.
full build log is here:

According to http://developers.sun.com/solaris/articles/sparcv9abi.html
this patch should help:

OCaml's native-code generator cannot generate Sparc 64 bits code. An unofficial port for Sparc64/Solaris exists (http://www.mit.edu/~jfc/) but was never integrated in the trunk by lack of resources. So, you're stuck with bytecode only. I'll try to fix the configure script so that it turns native compilation off on Sparc in 64-bit mode.
