While the commit bcab2ba2573784415a25688bc1b4c116f4b8cbc5 fixed the
multiline issue, it did not fix all of the issues related to ANSI style
prototype declarations:

% cat ee.c
#include "ee.h"

void main(void) {

return;
}


% cat ee.h
#define _PROTOTYPE(function, params) function params

#ifdef _MINIX
/* Signal handler type, e.g. SIG_IGN */
typedef void _PROTOTYPE( (*sighandler_t), (int) );
#else
typedef void ( * sighandler_t ) ( int ) ;
#endif

% ./libexec/scc/cc1 -D _MINIX -E ee.c

#line 2 "ee.h"

#line 4

ee.h:5: error: #endif expected
typedef void ee.h:5: error: #endif expected

% ./libexec/scc/cc1 -E ee.c

#line 2 "ee.h"

#line 7
typedef void ( * sighandler_t ) ( int ) ;

#line 2 "ee.c"

void main ( void ) {

return ;
}
#line 6


The output above is from FreeBSD 13.1, showing this is not a Minix issue
(Minix is just revealing these issues).
