This code has not worked for a long time. Most systems now maintain
the password entries so that a password is not accessible through the
getpwent() interface. The SUBR that calls this interface may be
removed at a future time.
We now can handle these via `inc/maiko/platform.h` and the
constants defined there.
This doesn't change `OS5` for Solaris yet as that's a much wider
set of changes.
The NOFORN flag controls foreign function interface code, which
was written using the dld_* APIs which haven't existed in years.
There was a GNU dld that provided this API, but it was withdrawn
in 2006.
If this code is to be re-enabled, it will have to be changed to
use the `dlopen` family of APIs.
* Always follow NEW_STORAGE code paths.
This removes the code paths for the pre-NEW_STORAGE code.
* Remove NEW_STORAGE from build system.
The code no longer refers to `NEW_STORAGE`, so we can remove
this from the build system.
The FSERROR define is on all the time now. It was not controlling
all of the functionality, with many places setting Lisp_errnno
outside of the code controlled by the define.
On SunOS4, we build `xc.c` by jumping through a lot of hoops to
perform a particular set of operations. We don't do that on other
platforms and this will help clean up the Linux and FreeBSD makefiles.
These directives were already not present in the macOS makefiles.
