 This version is needed because the fpos_t type and a few libio internals
 have changed in glibc 2.2, and gcc 2.95.3 contains a corresponding patch.

+2.36.	Why shall glibc never get installed on GNU/Linux systems in
+/usr/local?
+
+{AJ} The GNU C compiler treats /usr/local/include and /usr/local/lib in a
+special way, these directories will be searched before the system
+directories.  Since on GNU/Linux the system directories /usr/include and
+/usr/lib contain a --- possibly different --- version of glibc and mixing
+certain files from different glibc installations is not supported and will
+break, you risk breaking your complete system.  If you want to test a glibc
+installation, use another directory as argument to --prefix.  If you like to
+install this glibc version as default version, overriding the existing one,
+use --prefix=/usr and everything will go in the right places.
