This patch moves more includes (most of them, to tell the truth) to common/include directory. This completes the list of includes needed to compile current trunk with the new libc (but to do that you need more patches in queue). This patch also contains some modification (for compilation with new headers) to the common includes under __NBSD_LIBC, the define used in mk script to specialize compilation with new includes.

/* The <minix/ansi.h> header attempts to decide whether the compiler has enough
|
|
* conformance to Standard C for Minix to take advantage of. If so, the
|
|
* symbol _ANSI is defined (as 31459). Otherwise _ANSI is not defined
|
|
* here, but it may be defined by applications that want to bend the rules.
|
|
* The magic number in the definition is to inhibit unnecessary bending
|
|
* of the rules. (For consistency with the new '#ifdef _ANSI" tests in
|
|
* the headers, _ANSI should really be defined as nothing, but that would
|
|
* break many library routines that use "#if _ANSI".)
|
|
|
|
* If _ANSI ends up being defined, a macro
|
|
*
|
|
* _PROTOTYPE(function, params)
|
|
*
|
|
* is defined. This macro expands in different ways, generating either
|
|
* ANSI Standard C prototypes or old-style K&R (Kernighan & Ritchie)
|
|
* prototypes, as needed. Finally, some programs use _CONST, _VOIDSTAR etc
|
|
* in such a way that they are portable over both ANSI and K&R compilers.
|
|
* The appropriate macros are defined here.
