27d4fb96 87/* XXX A note on the perl source internal type system. The
88 original intent was that I32 be *exactly* 32 bits.
89
90 Currently, we only guarantee that I32 is *at least* 32 bits.
91 Specifically, if int is 64 bits, then so is I32. (This is the case
92 for the Cray.) This has the advantage of meshing nicely with
93 standard library calls (where we pass an I32 and the library is
94 expecting an int), but the disadvantage that an I32 is not 32 bits.
95 Andy Dougherty August 1996

dc45a647
MB		 97 There is no guarantee that there is *any* integral type with
98 exactly 32 bits. It is perfectly legal for a system to have
99 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 100

MB		 101 Similarly, there is no guarantee that I16 and U16 have exactly 16
102 bits.

8c52afec 502 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 503 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 504 (The main "offenders" are extensions.)
27d4fb96 505 Further, if you try LEAKTEST, you'll also end up calling
506 Safefree, which might call safexfree() on some things that weren't
507 malloced with safexmalloc. The correct "fix" to this, if anyone
508 is interested, is to ensure that all calls go through the New and
509 Renew macros.

514=for apidoc Am|SV*|NEWSV|int id|STRLEN len
515Creates a new SV. A non-zero C<len> parameter indicates the number of
516bytes of preallocated string space the SV should have. An extra byte for a
517tailing NUL is also reserved. (SvPOK is not set for the SV even if string
