Forest is not compliant with Posix.5 nor does it claim to be, see the
documentation which comes with the code. It uses the 1003.5-1992 standard.
Most of it follows the standard carefully and provides extensions in child
packages, which is within the guidelines specified by the standard.
However, there is one change which can cause problems for users.
Forest adds a new alternative to the type Signal_Masking, called Restart,
which specifies that the Posix.5 support should automatically handling
restarting of interupted actions. This is not a particularly bad extension
and it is easy to support, unfortunately Forest makes this the default value
for the signal masking parameter. This can provide suprises for client code
expecting the default value to be RTS_Signals or when moving to another
implementation of Posix.5 which does not support the Restart option.
