    33We are aware that Linux distributions and embedded systems vendors like to be able to compile everything with the same system build toolchain, which may be very old, so we have compromised with Apple to develop a [[DependenciesPolicy]] that attempts to balance the interests of both WebKit distributors and developers. We intend to support some system compiler in the latest Ubuntu LTS and Debian stable releases until one year after the subsequent release, but, depending on the age of the release, this might be some version of Clang rather than GCC. We no longer provide any timeline as to how long a particular version of GCC may be supported, as this decision will be made by WebKit developers on a case-by-case basis. However, we will always support the version of libstdc++ available in these releases until one year after the subsequent release. Preserving compatibility with older standard library versions is necessary to allow updates on older systems, even if a newer compiler is used to build those updates. In general, you can expect a new standard library version to be supported by WebKit for approximately three to four years, in accordance with the dependencies policy.

    5 This policy means that WebKit may require a new version of GCC sooner than you might prefer. Because Apple does not use GCC to develop WebKit, and because of the relatively high number of compatibility issues caused by supporting GCC, we should be grateful that it is still possible to build WebKit with GCC at all. Unless you are able to upgrade your systems to newer GCCs on a regular basis, it is expected that your system GCC may not be new enough to build WebKit. We urge you to consider building with a different compiler if your system compiler is too old. If you choose to stop building new versions of WebKit as a result of an increased GCC version requirement, rather than building with a newer compiler, your users will be left vulnerable to numerous security vulnerabilities that are fixed in newer versions.

Embedded systems vendors may choose to deploy WebKit in a container if updating the host's libstdc++ is undesirable. If you choose to stop building new versions of WebKit as a result of an increased GCC or libstdc++ version requirement, your users will be left vulnerable to numerous security vulnerabilities that are fixed in newer versions.
