% added optional compilation HVM core files as single unit.
It allows to use interprocedural optimizations for all defined
functions. It's useful when compiler does not support IPO at link
time. It should give some noticeable speed improvement for compilers
which can benefit from such optimizations, f.e. GCC, ICC, MSVC.
In my Linux box (GCC 4.3) it gives ~7% speed improvement in
speedtst.prg linked with ST HVM and a little bit more in MT mode.
It's interesting that it also reduces the HVM library size.
At least for GCC builds.
Set HB_HVM_ALL=yes envvar to enable such compilation.
Warning some compiler may not compile such long single C file.
