dnl We expect to see the declaration of sleep() in a header file.
dnl Older versions of mingw have a sleep() function that is an alias to
dnl _sleep() in MSVCRT. It has a different signature than POSIX sleep():
dnl it takes the number of milliseconds as argument and returns void.
dnl mingw does not declare this function.
