Was hit with this when compiling wine 1.7.51 on 64-bit proot 5.1.0 and using debian squeeze i386 as guest: ``` ../configure: xmalloc: ../bash/make_cmd.c:100: cannot allocate 2282628 bytes (13500416 bytes allocated)...

[mmap(2)](https://www.gnu.org/software/libc/manual/html_node/Memory_002dmapped-I_002fO.html) allows to use files larger than available RAM.
