Unfortunately, the patch doesn't help at all.  I've instrumented
fix-header.c (recognized_function) to print the function declarations
scan-decls.c (scan_decls) finds: the old version (before the patch in
question) finds a long list of declarations, kill among them:

signal.h: OK, nothing needs to be done.

The current version only finds four function declarations instead, with
kill missing, so the broken prototype is inserted.

% ./fix-header signal.h include/signal.h include/signal.h -D__STDC__=0 -D__cplusplus -Iinclude -I/usr/include
recognized_function (name = _sysconf line = 974 kind = F have_arg_list = 1)
recognized_function (name = SIG_FUNC_TYP line = 980 kind = F have_arg_list = 1)
recognized_function (name = signal line = 1035 kind = F have_arg_list = 1)
recognized_function (name = raise line = 1039 kind = F have_arg_list = 1)
signal.h: 1 missing function declarations.

I have no idea yet what causes this difference and considerable differences
in line numbers for the declarations that are found in both versions (and
need to go to bed now).
