svn commit: r608282 - /incubator/stdcxx/trunk/bin/xbuildgen

[se...@apache.org]

Author: sebor
Date: Wed Jan  2 15:36:55 2008
New Revision: 608282

URL: http://svn.apache.org/viewvc?rev=608282&view=rev
Log:
2008-01-02  Martin Sebor  <se...@roguewave.com>

	* xbuildgen: Avoided division by zero errors in cases when the library
	failed to build in all logs (or its size couldn't be determined as is
	still the case on Windows). Ditto for build sizes.
	(format_size): Handled empty sizes.
