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