[AD] dat2c bugfixes

[rpgrca@xxxxxxxxxx]

Some issues with dat2c.c:
1. Didn't free memory allocated by cvt_FONT_color
2. Allocating 4 bytes (rather than 5) to allocate "data"
3. Overflow because of allocating not enough memory.

This bug was found with DJGPP 2.3 (GCC 2.952), Allegro WIP 4.1.2. The
following patch fixes them all.
