+Subject: [PATCH] Fix build race in Makefile
+
+The current rule for the binaries is:
+
+glew.bin: glew.lib bin bin/$(GLEWINFO.BIN) bin/$(VISUALINFO.BIN)
+
+In parallel builds, all of those targets happen at the same time. This
+means that 'bin' can happen *after* 'bin/$(GLEWINFO.BIN)', which is a
+problem as the 'bin' target's responsibility is to create the directory
+that the other target writes into.
+
+Solve this by not having a separate 'create directory' target which is
+fundamentally racy, and simply mkdir in each target which writes into it.
