[svn-r19808] Purpose:
Add "--enable-unsupported" configure flag.
Description
The "--enable-unsupported" configure flag allows a user to
prevent configure from failing due to the use of incompatible
options, such as c++ with parallel.
Specifying --enable-unsupported will bypass all of configure's
checks for incompatible and unsupported combinations of flags.
There are no guarantees that the library will be configured
in any sort of working condition, but that's the risk of
using the --enable-unsupported flag.
I've changed all default error messages related to unsupported
option combinations to indicate that using --enable-unsupported
will allow configure to complete without error.
Tested:
by hand on jam, tested all unsupported configure option
combinations with and without the new flag, making sure
the flag allows configure to finish without error.
(h5committest wouldn't do any good here; it won't test
the new option, and since we're enabling unsupported
combinations, failures are likely to occur in build or
tests with --enable-unsupported turned on anyways.
That's why they're unsupported!)
