Re-registering an existing suffix for a type fails erroneously, patch attached

[anonymous]

I've attached a patch against the development trunk that indicates what I believe is a problem in tools/build/v2/build/type.jam .

The comments and the code suggest that re-registering a suffix to a type should be okay. I've included a snippet from the current trunk below.

# Specifies that files with suffix from 'suffixes' be recognized as targets of
# type 'type'. Issues an error if a different type is already specified for any
# of the suffixes.
#
rule register-suffixes ( suffixes + : type )
{
    for local s in $(suffixes)
    {
        if ! $(.type.$(s))
        {
            .type.$(s) = $(type) ;
        }
        else if $(.type.$(s)) != type
        {
            errors.error Attempting to specify multiple types for suffix
                \"$(s)\" : "Old type $(.type.$(s)), New type $(type)" ;
        }
    }
}

(In [51240]) Use $(type) instead of type. Fixes #2648
