Hi,

The addr_t type is used in memory managment (memory addresses??) in /usr/include/sys/mman.h. If you plan on using this (or is already on the code, mman.h i mean) you may have problems. What is the type of your addr_t? is it type char of * (pointer)?

If the code is open source you can just change the addr_t typedef name (in your source) to something else eg. addr2_t in all of your source files (a simple search and replace).
