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