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-glibc21-linux
