89 original intent was that I32 be *exactly* 32 bits.
90
91 Currently, we only guarantee that I32 is *at least* 32 bits.
92 Specifically, if int is 64 bits, then so is I32. (This is the case
93 for the Cray.) This has the advantage of meshing nicely with
94 standard library calls (where we pass an I32 and the library is
95 expecting an int), but the disadvantage that an I32 is not 32 bits.

98 There is no guarantee that there is *any* integral type with
99 exactly 32 bits. It is perfectly legal for a system to have
100 sizeof(short) == sizeof(int) == sizeof(long) == 8.
693762b4 101

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

8c52afec 512 XXX LEAKTEST doesn't really work in perl5. There are direct calls to
27d4fb96 513 safemalloc() in the source, so LEAKTEST won't pick them up.
c1d22f6b 514 (The main "offenders" are extensions.)
27d4fb96 515 Further, if you try LEAKTEST, you'll also end up calling
516 Safefree, which might call safexfree() on some things that weren't
517 malloced with safexmalloc. The correct "fix" to this, if anyone
518 is interested, is to ensure that all calls go through the New and
519 Renew macros.

526=for apidoc Am|SV*|NEWSV|int id|STRLEN len
527Creates a new SV. A non-zero C<len> parameter indicates the number of
528bytes of preallocated string space the SV should have. An extra byte for a
529tailing NUL is also reserved. (SvPOK is not set for the SV even if string
8e84507e 530space is allocated.) The reference count for the new SV is set to 1.
