Z:gnu-www-ja-gpl-faq--ca9a5f-The criteria for what counts a/en

The criteria for what counts as a &quot;system library&quot; vary between different versions of the GPL. GPLv3 explicitly defines &quot;System Libraries&quot; in section 1, to exclude it from the definition of &quot;Corresponding Source.&quot; GPLv2 deals with this issue slightly differently, near the end of section 3.
