+(32-bit x86) functions. On Solaris~8, you need 108993-26 or newer on
+SPARC, 108994-26 or newer on Intel. On Solaris~9, the necessary support
+on SPARC is present since FCS, while 114432-05 or newer is reqired on
+Intel. Additionally, on Solaris~8, patch 109147-14 or newer on SPARC or
+109148-22 or newer on Intel are required for the Sun @command{ld} and
+runtime linker (@command{ld.so.1}) support. Again, Solaris~9/SPARC
+works since FCS, while 113986-02 is required on Intel. The linker
+patches must be installed even if GNU @command{ld} is used. Sun
+@command{as} in Solaris~8 and 9 doesn't support the necessary
+relocations, so GNU @command{as} must be used. The @command{configure}
+script checks for those prerequisites and automatically enables TLS
+support if they are met. Although those minimal patch versions should
+work, it is recommended to use the latest patch versions which include
+additional bug fixes.
