No, there isn't, at least I haven't found one.  The BK installer does 
exactly what you want (and you can have the source if you like, BSD 
license) on the platforms listed below.  We had to play some nasty 
games to make this work, I believe it was HP-UX which "knew" that your
array was full of zeros and did not allocate it, it did it at runtime.
Any sort of predictable pattern it figured out, the following fools it
for now:

unsigned char data_data[3866327] = {
        255,
        6,
        1,
        2,
        3,
        4,
        255,
        3,
        9,
        62,
        255,
        10,
        4,
        61,
        255,
};

platforms that this technique works on:

    alpha-glibc22-linux
    alpha-osf5.1
    arm-glibc21-linux
    hppa-glibc22-linux
    hppa-hpux
    ia64-glibc22-linux
    mips-glibc22-linux
    mips-irix
    mipsel-glibc20-linux
    powerpc-aix
    powerpc-darwin6.6
    powerpc-glibc21-linux
    sparc-glibc21-linux
    sparc-solaris
    x86-freebsd2.2.8
    x86-freebsd3.2
    x86-freebsd4.1
    x86-glibc20-linux
    x86-glibc21-linux
    x86-glibc22-linux
    x86-netbsd
    x86-openbsd
    x86-sco3.2v5.0.7
    x86-solaris
