While I was not looking, some of them were corrected:

commit d7df0b41dc38327388c3f19fdf4246793d4a1e4b
Author: Marc-André Lureau <marcandre.lureau@redhat.com>

    slirp: prefer c99 types over BSD kind

    Replace:
    - u_char -> uint8_t
    - u_short -> uint16_t
    - u_long -> uint32_t
    - u_int -> unsigned
    - caddr_t -> char *

grep " uint;" on my system includes.  I know that there are more
creative ways to define it.

/usr/include/ffi-x86_64.h\0278:  ffi_arg   uint;
/usr/include/sys/types.h\0150:typedef unsigned int uint;

#ifdef __USE_MISC
/* Old compatibility names for C types.  */
typedef unsigned long int ulong;
typedef unsigned short int ushort;
typedef unsigned int uint;
#endif

I guess we get those someway.

/usr/include/nspr4/obsolete/protypes.h\052:typedef PRUintn uint;
/usr/include/mysql/server/my_global.h\0465:typedef unsigned int uint;
/usr/include/boost/iostreams/filter/zlib.hpp\047:typedef uint32_t uint;
/usr/include/qt5/QtCore/qglobal.h\0275:typedef unsigned int uint;

in qt it is defined for everything.

If I disable the ones in sys/types.h

I got:

There are some other friends that fail in linux-user/syscall.c

I will post an RFC with my findings.

Later, Juan.
