Hi,
I'm trying to compile uClibc using buildroot, but I get these error messages:
CC libc/sysdeps/linux/common/mmap64.os
libc/sysdeps/linux/common/mmap64.c: In function 'mmap64':
libc/sysdeps/linux/common/mmap64.c:66: error: '__ulong_t' undeclared
(first use in this function)
libc/sysdeps/linux/common/mmap64.c:66: error: (Each undeclared
identifier is reported only once
libc/sysdeps/linux/common/mmap64.c:66: error: for each function it appears in.)
libc/sysdeps/linux/common/mmap64.c:66: error: expected ')' before 'offset'
For this problem I made the attached patch, after applying that mmap64
compiles fine.
But I still get other errors:

These are 128-bit float functions, right? Can I disable 128-bit
floating point arithmetic somehow? No Sparc CPUs implement the
instructions anyway.
