Move _heap.h to the compiler include dir. Create heap.inc and use that from the assembler code. Rename heap related _h... variables to _heap... Add _heapmaxavail and _heapmemavail functions. git-svn-id: svn://svn.cc65.org/cc65/trunk@1912 b7a2c559-68d2-44c3-8de9-860c34a00d81 2003-02-01 12:22:09 +00:00			`.include "_heap.inc"`
