The header-only static-inline error()/error_at_line() collided with gnulib's own
lib/error.c ('redefinition of error', building m4): autotools link-detects a
system error(), skips its replacement, then the inline in <error.h> clashes with
gnulib's definition. Implement them properly in relibc (src/header/error) with
the glibc globals (error_message_count, error_one_per_line, error_print_progname)
and make <error.h> a pure extern declaration. Fixes m4/gnulib and keeps
mesa/libelf (the original <error.h> consumers) working via the real symbol.

/* error.h — GNU-style error reporting.
|

*
|
|
* Red Bear OS / relibc. Mirrors glibc <error.h>: error() and error_at_line()
|
|
* print the program name (best effort), a formatted message, and optionally a
|
|
* strerror() of errnum to stderr, then exit() when status is non-zero.
|
|
*
|
|
* These are DECLARED here and IMPLEMENTED as real exported symbols in relibc
|
|
* (src/header/error). They must NOT be static-inline: autotools/gnulib link-test
|
|
* for a system error() and, finding one, skip compiling their own lib/error.c —
|
|
* a header-only inline collides with that replacement ("redefinition of
|
|
* 'error'", seen building m4/gnulib).
