You might need to do #exe {Option();}.5 6OPTf_GLBLS_ON_DATA_HEAP without this option, global vars are placed in the code7heap which is limited to 2Gig.  In AOT modules, global vars take-up room in the8.BIN file, so you might want to use this option, instead.  You might wish to9turn it on and off around specific vars.  A disadvantage of data heap global10vars in AOT modules is they can't be initialized.11 12OPTf_EXTERNS_TO_IMPORTS and OPTf_KEEP_PRIVATE are strange options, you'll never13need.  They're to allow the same header file for Kernel to act as externs when14compiling itself and imports when compiled by AOT modules.15 16OPTf_WARN_UNUSED_VAR    warning if unused var.  It is applied to functions.17 18OPTf_WARN_PAREN         warning if parenthesis are not needed.19 20OPTf_WARN_DUP_TYPES     warning if dup local var type stmts.21 22OPTf_WARN_HEADER_MISMATCH warning if fun header does not match.23 24OPTf_NO_REG_VAR forces all function local vars to the stk not regs.
