The pthread_incomplete_struct_argument fix was intended for ancient versions of Glibc (only 2.3.3 and 2.3.4, I believe). From Glibc 2.3.5 the pthread.h header already included the change to use a pointer instead of an array, so the fixinclude was no longer used. However, the https://sourceware.org/bugzilla/show_bug.cgi?id=26647 fix changed the __setjmpbuf declaration to use struct __jmp_buf_tag __env[1] again, which caused this fixinclude to start matching again. This means that GCC now installs a "fixed" pthread.h with a change to a declaration that guarded by #if ! __GNUC_PREREQ (11, 0), i.e. it's not even relevant for modern versions of GCC. The "fixed" pthread.h causes problems for users because of changes to internal implementation details of the pthread_cond_t type, which require the "fixed" pthread.h to be updated with mkheaders if Glibc is updated. This change adds a bypass to the fixinclude, so that it no longer matches modern Glibc versions, and only applies to glibc versions 2.3.3 and 2.3.4 as originally intended.
