Comment (by jprostko):
Known issue 3:
After the x86_64 merge, Haiku will not compile all that far with GCC 4.7.2
for an x86 build. I get the following error post-hrev44541:
{{{
C++ /home/jprostko/haiku-exp/haiku/generated-
gcc4/objects/haiku/x86/release/system/kernel/arch/x86/apm.o
/home/jprostko/haiku-exp/haiku/src/system/kernel/arch/x86/32/apm.cpp:

error: cannot bind packed field
'args->kernel_args::platform_args.platform_kernel_args::apm' to
'apm_info&'
}}}
I'm not sure why GCC 4.6.3 chugs along happily, but GCC 4.7.2 complains.
I'm not sure if one struct is declared packed and another one isn't? I
admit I got distracted from investigating this, as I was trying to find
some good way to handle the cross-compiler situation in "Known issue 1".
There may be more issues to uncover, as I have only been doing my testing
so far building x86 buildtools for the most part. As such, I want to test
at least x86_64 as well, to make sure everything builds fine, and to
perhaps uncover any other issues.
