Looking into /usr/include/stdlib.h, there's a `devname()` function defined
under some #ifdef's which conflicts with the `static char *devname` definition
in `src/mkwrggimg.c`.
Defining `_ANSI_SOURCE` in the `src/mkwrggimg.c` file, omits that part of the
header.
Another more intrusive approach is to rename `devname` to something like
`g_devname` in `src/mkwrggimg.c`. But I think the `_ANSI_SOURCE` define should
be enough.
Compilation error is:
