If several lines contain similar code, put similar things below each other (see a and b);
Put spaces between operands and operators
Put braces {}, brackets [] and parentheses () below each other (d) if there is much code between. 
Brackets and parentheses may be in one line if the code between is small (c)
Indent by 4 Spaces. Two indent levels may be abbreviated by one tab.

So create the structure that matches your data (linked lists, trees, arrays, etc) and what to do with them (sorting, searching, etc)

.h usually contain #define #include typedef enum struct extern screen and window definitions (data structures)
.c should contains functions and algorithms

Library:
   - Private data structure
   - Many public access methods

Device:
   - Private data structure
   - Two (BeginIO/AbortIO) access methods

Resource:
   - Public data structure
   - *NO* access methods

Summary - In short:

* build AROS with debugging support (i.e. ./configure --enable-debug=all)
* build your application with debugging support (i.e. option -g)
* run AROS in the GNU debugger (you may use the GUI frontend "ddd" which simplifies usage a bit)
* start your application
* use the commands "findaddr" and "add-symbol-file" as written in the debugging manual
* if the debugger doesn't find the source code of your application use the "dir" command of the debugger. 

./configure—enable-debug—with-optimization="-O2"

--with-optimization=-"-O2 -fno-strict-aliasing"

1. BYTE/UBYTE is 8bit, WORD/UWORD is 16bit, LONG/ULONG is 32bit, QUAD/UQUAD is 64bit, the types are comparable with stdint types (int8_t, int16_t, int32_t, int64_t)
2. IPTR/SIPTR are integer types large enough to fit pointer, that is sizeof(IPTR) = sizeof(APTR) = 4 on 32bit system, and = 8 on 64bit system
3. ti_Data in TagList is large enough to hold a IPTR/APTR type.
4. never store a pointer in integer of type LONG. It may work (if the pointer has upper 32bits clear), but does not have to. Compiler should warn you about that.
5. If you are unsure about point 4, allocate your memory with MEMF_31BIT flag set. But don't expect that AROS internals will do the same.

UBYTE    Unsigned 8 bit integer variable (byte).
BYTE     Signed 8 bit integer variable (byte).
UWORD    Unsigned 16 bit integer variable (word).
WORD     Signed 16 bit integer variable (word).
ULONG    Unsigned 32 bit integer variable (longword).
LONG     Signed 32 bit integer variable (longword).
FLOAT    32 bit IEEE floating point variable.
UQUAD    Unsigned 64 bit integer variable.
QUAD     Signed 64 bit integer variable.
DOUBLE   64bit IEEE floating point variable.
BOOL     Boolean variable, TRUE and FALSE are also defined in exec/types.h.
VOID     Void.

APTR     A generic pointer for multiple purposes - Arrays.
STRPTR   A pointer to a null-terminated string.
IPTR     Really important in AROS, the only way to declare a field that can contain both: an integer or a pointer.

In the future...?

 - This also allows every window to be on its own 3D surface with backing store, allowing Wanderer (or a Commodity)

 - Yes, it will require a lot of work in the libraries to make this transition
 - Yes, I do think it will be worth it in the end.
