I saw this the other day in a script that installs win32-pthreads:

for file in 'pthread.h' 'sched.h' 'semaphore.h'; do
  ed -s "$prefix/include/$file" <<< $'g/ __declspec (dllexport)/s///g\nw\nq'
  ed -s "$prefix/include/$file" <<< $'g/ __declspec (dllimport)/s///g\nw\nq'
done

I'll admit that it is a bit frustrating to have to do
 export CFLAGS=-DPTW32_STATIC_LIB
for anything that ends up using pthreads...

FWIW.
