Oliver Schmidt d001a6f1a0 Have _heapmaxavail() work as advertised. 
The cc65 doc explicitly states that the return value of _heapmaxavail() can be used as parameter of malloc(). To actually allow for that the size of HEAP_ADMIN_SPACE has to be substracted from the raw size of the largest free heap block.

build status

cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools.

cc65 has C and runtime library support for many of the old 6502 machines, including

  • the following Commodore machines:
    • VIC20
    • C16/C116 and Plus/4
    • C64
    • C128
    • CBM 510 (aka P500)
    • the 600/700 family
    • newer PET machines (not 2001).
  • the Apple ][+ and successors.
  • the Atari 8 bit machines.
  • GEOS for the C64 and C128.
  • the Nintendo Entertainment System (NES).
  • the Supervision console.
  • the Oric Atmos.
  • the Lynx console.

The libraries are fairly portable, so creating a version for other 6502s shouldn't be too much work.
