Re: [PATCH] unexec() for Cygwin port

[Eli Zaretskii <eliz@elta.co.il>]

Btw, the function reproduced below should use a case-insensitive
comparison to the ".exe" string, as I'm sure you didn't mean that the
dumping should fail when some weirdo shell or Make hands you a name
like "EMACS.EXE" instead of the expected "emacs.exe".

+static char *
+add_exe_suffix_if_necessary(const char *name, char *modified)
+{
+	int i = strlen(name);
+	if (i <= (sizeof(DOTEXE) - 1)) {
+		sprintf(modified, "%s%s", name, DOTEXE);
+	} else if (!strcmp(name + i - (sizeof(DOTEXE) - 1), DOTEXE)) {
+		strcpy(modified, name);
+	} else {
+		sprintf(modified, "%s%s", name, DOTEXE);
+	}
+	return(modified);
+}
