umm..
you might not change anything with these at Pawn.sublime-build:
PHP код:
{
    "cmd": ["${project_path:${folder}}/pawncc.exe", "$file_name", "-;+", "-v2", "-d3", "-\\)+"],
    "working_dir": "${file_path}",
    "file_regex": "^([^\\.]+\\.pwn)\\((\\d+)\\)() : (.*)$",
    "variants": [
        {
            "cmd": ["${project_path:${folder}}/pawncc.exe", "$file_name", "-;+", "-v2", "-d3", "-\\)+", "-l"],
            "working_dir": "${file_path}",
            "name": "Preprocessed output"
        },
        {
            "cmd": ["${project_path:${folder}}/pawncc.exe", "$file_name", "-;+", "-v2", "-d3", "-\\)+", "-a"],
            "working_dir": "${file_path}",
            "name": "P-code output"
        }
    ]
} 
 and do -> Project -> Add Folder to Project -> select your pawno folder.
it might work good.
final check what build system do you use at Tool -> Build System
cause when you build, it will do like pawno,
compile that pwn and make amx in same document as i know..
but maybe im fault or x___x
buy the way , you can change or add compile options at  , "-;+", "-v2", "-d3", "-\\)+", "-l"],
