39d1d32c3dSAlex Richardson  * On some versions of glibc including string.h before stdlib.h won't work.
40d1d32c3dSAlex Richardson  * This happens when building anything that uses the libnetbsd stdlib.h
41d1d32c3dSAlex Richardson  * override. This is because string.h will include stdlib.h with a flag set to
42d1d32c3dSAlex Richardson  * define only a subset of the functions (which will then not set the _STDLIB_H
43d1d32c3dSAlex Richardson  * macro). libnetbsd stdlib.h can only be included once so this will not work.
