PaweĊ‚,

there's an issue with changes like that one bellow.
Currently each file including compat.h have to include
config.h before on its own. That does not sound too
convenient and is quite error prone as I just found
testing mkdir patch on more configurations.

So what about this change:

diff --git a/include/compat.h b/include/compat.h
index 8711c425..60974344 100644
--- a/include/compat.h
+++ b/include/compat.h
@@ -18,6 +18,17 @@
 #ifndef        _gnokii_compat_h
 #define        _gnokii_compat_h
 
+#if defined(HAVE_CONFIG_H)
+#  include "config.h"
+
+#elif defined(WIN32) && defined(_MSC_VER)
+#  include "windows-config.h"
+
+#else
+#  error "compat.h requires config.h"
+
+#endif
+
 #include <stdlib.h>
 #include <stdio.h>

Perhaps ommiting windows-config.h part in the first round.
Then we could delete config.h include from each file which
also include compat.h. That is... almost each file.

Objections?
