* dumper.h: Remove pdump_objects_unmark.
* lrecord.h (DUMPEDP): Dumped objects can be freed, remove.
DUMP_IN_EXEC:
* Makefile.in.in: Linking for and with dump in executable only if
DUMP_IN_EXEC is defined.
* config.h.in: Add new flag `DUMP_IN_EXEC'
* emacs.c: Condition dump-data.h on DUMP_IN_EXEC.
* emacs.c (main_1): Flag `-si' only works if dump image is
written into executable.
Miscellanious
* lrecord.h (enum lrecord_type): Added numbers to all types,
very handy for debugging.
* xemacs.def.in.in: Add mc-alloc functions to make them visible
to the modules.

| 255 around that is with a union. The macros below help out, e.g. the | |
| 256 definition of XE_MAKEPOINTS(val) is | |
| 257 | |
| 258 ANSI_ALIASING_TYPEDEF (POINTS, POINTS); | |

| 265 On the other hand, if you are just casting from one pointer to the other | |
| 266 in order to pass a pointer to another function, it's probably OK to just | |
| 267 trick GCC by inserting an intermediate cast to (void *), to avoid | |
| 268 warnings about "dereferencing type-punned pointer". #### I don't know | |
| 269 how kosher this is, but do strict-aliasing rules really apply across | |
| 270 functions? | |
| 271 | |
| 272 Note that the input to e.g. VOIDP_CAST must be an lvalue (i.e. not | |
| 273 &(something)), but the value of the macro is also an lvalue, so in place | |
| 274 of `(void **) &foo' you could write `& VOIDP_CAST (foo)' if you are | |
| 275 subsequently dereferencing the value or don't feel comfortable doing a | |
| 276 trick like `(void **) (void *) &foo'. | |
| 277 | |
| 278 Unfortunately, it does not work to just define the union type on the fly in | |
| 279 the cast -- otherwise, we could avoid the need for a typedef. Or rather, | |
| 280 it does work under gcc but not under Visual C++. | |
