41  * On some versions of glibc including string.h before stdlib.h won't work.
42  * This happens when building anything that uses the libnetbsd stdlib.h
43  * override. This is because string.h will include stdlib.h with a flag set to
44  * define only a subset of the functions (which will then not set the _STDLIB_H
45  * macro). libnetbsd stdlib.h can only be included once so this will not work.
