[Bug java/21714] New: libjava bootstrap failure in java/lang/natConcreteProcess.cc

[cato at df dot lth dot se]

Bootstrapping gcc "4.1.0 20050521 (experimental)" fails when compiling libjava:
  java/lang/natConcreteProcess.cc:25:21: error: pthread.h: No such file or directory
  java/lang/natConcreteProcess.cc: In member function 'void
java::lang::ConcreteProcess$ProcessManager::init()':
  java/lang/natConcreteProcess.cc:105: error: 'pthread_self' was not declared in
this scope

because NetBSD 1.6 does not have threads.

This is a regression, since bootstrapping gcc 3.4 works.

Huh, are you sure it does not have pthreads.

Yes, I am sure.  pthreads were added in the NetBSD 2.0 release.

I don't think we should revert it as Process et al. were broken on many pthread
targets before the patch.

Since NetBSD is not posix, perhaps it should not be using PosixProcess.  I am
not a BSD hacker so I cannot fix it.

I agree, we should definitely not revert this.
Instead someone should make this file compile and try to work ok
when no threads are available.  Or, if that can't be done,
make a new natBSDProcess.cc.

 in java/lang/natConcreteProcess.cc

This is not a BSD problem -- it is just that NetBSD 1.6 is old enough
that threads were not as pervasive as they are now (and NetBSD takes
long term maintenance seriously, so 1.6 is still a maintained release
branch).

What are the problems with the old implementation?  Would it make
sense to resurrect it as natProcessNoThread.c or something?
