While building latest gdal

the following bloc of
/usr/include/sys/types.h

-----------------------------------------------------------------------
#if __MISC_VISIBLE
typedef unsigned short  ushort;         /* System V compatibility */
typedef unsigned int    uint;           /* System V compatibility */
typedef unsigned long   ulong;          /* System V compatibility */
#endif
-------------------------------------------------------------------------

seems to cause a puzzling recursive definition
(as reported by g++ -C -E)

$ grep "System V" ../o/.libs/jpeg2000_vsil_io.E
typedef unsigned short unsigned short; /* System V compatibility */
typedef unsigned int unsigned int; /* System V compatibility */
typedef unsigned long unsigned long; /* System V compatibility */
  * from System V, which stupidly took internal interface macros and

however I don't see how the definition is read two times
or where ushort was previoulsy defined.

grep "ushort" ../o/.libs/jpeg2000_vsil_io.E
<empty>

What I am missing ?

Regards
Marco
