[bug-libunistring] Compiling libunistring-0.9.3 on AIX

[Perry Smith]

I'm on AIX 6.1 TL07 SP03.

I tried just "configure" (followed by "make") and the link failed to find the 
pthread routines such as pthread_mutexattr_init

I then added --enable-threads=posix but no change.  Finally I did:

export CFLAGS=-pthread

and that worked.  Before this, the link calls did not have -lpthread and the 
calls to the compiler did not have -pthread.  I thought to be totally thread 
safe, you need both.

Hope this helps someone,
