+Description: zlib largefile function renaming
+ zlib include files can define the following preprocessor defines which
+ rename the corresponding PHP functions to gzopen64, gzseek64 and
+ gztell64 and thereby breaking some software, most notably PEAR's
+ Archive_Tar, which halts execution without error message on gzip
+ compressed archivesa.
+
+ This only seems to happen on 32bit systems with large file support.
