[Swig-cvs] SWIG/Lib/ruby rubystrings.swg,1.1,1.2

[Lyle J. <ly...@us...>]

Update of /cvsroot/swig/SWIG/Lib/ruby
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20022

Modified Files:
	rubystrings.swg 
Log Message:
Modified the "varin" typemap for a dimensionless char array to generate
a warning message, and to raise an exception if the typemap is actually
invoked at runtime. This is needed to avoid problems for the case when
wrapping an extern char[] declaration, where the array size is truly
unknown.
