I noticed that a few compressed archives files are using more size than their uncompressed form. For example, the libstdc++6-6.4.0-1.tar.xz file uses more space than its uncompressed tar file (on cygwin x86_64). That is not surprising. All compression methods may sometimes inflate the final amount of data. Would it be a way to keep the tar archive file uncompressed if the compressed form needs more space ?
