Some small fixes:

1) Should be said somewhere that the static lib must be build with this
option:

-lws2_32

2) In ptw32_MCS_lock.c, should be

#include "pthread.h"
#include "implement.h"

not

#include "implement.h"
#include "pthread.h"

3) gcc proto missing warnings:

gcc -c -o pthread_spin_lock.o -D__CLEANUP_C -O3 -finline-functions
-DPTW32_STATI
C_LIB -I. -DHAVE_CONFIG_H -Wall  pthread_spin_lock.c

pthread_spin_lock.c: In function `pthread_spin_lock':
pthread_spin_lock.c:55: warning: implicit declaration of function
`ptw32_spinloc
k_check_need_init'


gcc -c -o pthread_spin_trylock.o -D__CLEANUP_C -O3 -finline-functions
-DPTW32_ST
ATIC_LIB -I. -DHAVE_CONFIG_H -Wall  pthread_spin_trylock.c

pthread_spin_trylock.c: In function `pthread_spin_trylock':
pthread_spin_trylock.c:55: warning: implicit declaration of function
`ptw32_spin
lock_check_need_init'
