If anyone is interesting fixing FreeBSD's C compiler, it would be appreciated. % cat foo.c #include <stdio.h> #include <unistd.h> void foo(int i) { if (i < 0) goto whoops; if (i == 0) printf("foo\n"); if (i > 0) goto corrupt; return; whoops: printf("whoops\n"); return corrupt: printf("corrupt\n"); } % cc -c foo.c foo.c:21:1: error: use of undeclared identifier 'corrupt'; did you mean 'crypt'? corrupt: ^~~~~~~ crypt /usr/include/unistd.h:450:7: note: 'crypt' declared here char *crypt(const char *, const char *); ^ foo.c:21:8: error: expected ';' after return statement corrupt: ^ ; foo.c:14:12: error: use of undeclared label 'corrupt' goto corrupt; ^ 3 errors generated. No, I did not mean crypt. 'corrupt' is a defined label. The missing semicolon occurs in line 19, but the line is not properly identified in error output. -- Steve
