Avoid overflow in COLR bounds checks.
...
The values read into `base_glyphs_offset_v1` and `layer_offset_v1` may
be in the range 0xFFFFFFFD-0xFFFFFFFF. On systems where `unsigned long`
is 32 bits adding 4 to such values will wrap and pass bounds checks but
accessing values at such offsets will be out of bounds.
On the other hand `table_size` has already been tested to be at least
`COLRV1_HEADER_SIZE` (34) so it is safe to subtract 4 from it.
* src/sfnt/ttcolr.c (tt_face_load_colr): subtract 4 from `table_size`
instead of adding 4 to font data offsets in bounds checks

* vms_make.com: Provide separate library compiled with C++.
...
Some types on OpenVMS x86_64 (for example, `long') have different sizes
depending on whether compiled with either C or C++. In particular,
X-Windows applications crash if linked with the C++ version.
This patch makes `vms_make.com` create a second version of the FreeType
library compiled with C++ if OpenVMS is running on the x86_64 platform.
