Yes, an app shoudl be fine if it uses the public header files and system installed libtiff. If an app builds the libtiff (e.g. porting to a Portable Media Player), then the developers may think twice upgrading to 3.8.2. A related issue I found is the use of #ifdef WORDS_BIGENDIAN ...1 #else ...2 #endif Section 1 is used if you do #define WORDS_BIGENDIAN 0 and hope for section 2. The other def HOST_ENDIAN is not in use and it is either 0 or 1. The use of WORDS_ENDIAN doesn't really improve performance. Ping
