5 * Various systems get these things wrong. So
6 * we create a small compat library for them.

10 * - "string to long double" (C99 strtold())
11 * Missing in Solaris and MinGW

17 * Our "blob" allocator works on chunks that are multiples
18 * of this size (the underlying allocator may be a mmap that
19 * cannot handle smaller chunks, for example, so trying to
20 * allocate blobs that aren't aligned is not going to work).
