- Added support for ELF shared objects and libraries. This is implemented through constructor/destructor functions, which means that you can use this functionality even in Amiga Exec style shared libraries, with the proper library initialization code to invoke the constructor/destructor functions for you. - Updated uname() to recognize AmigaOS 4.1. - The translation from Unix to Amiga path names did not properly process multiple occurences of "/./" in the path name. Thanks go to Steven Solie for finding the issue. - The detection of "/./" and "/../" patterns in Unix path names to be translated into Amiga path names did not test if it was overrunning the end of the string. - If strcmp(), strncmp() and memcmp() detect a pair of different characters, then the function result must be calculated as if the characters were of type "unsigned char". This is a requirement according to the ISO 'C' (1994) standard. Thanks go to Georg Steger for finding the issue. - The definitions for INT_MIN, INT_MAX and UINT_MAX in <limits.h> no longer use long integer types, as prompted by Steven Solie. git-svn-id: file:///Users/olsen/Code/migration-svn-zu-git/logical-line-staging/clib2/trunk@15204 87f5fb63-7c3d-0410-a384-fd976d0f7a62
