make-emacs [options] ...
Build Emacs.
--help show this help
--all make clean versionclean first
--boot make boostrap, log to boot.log
--enable-checking ENABLE_CHECKING=1 (implies Lisp union type)
--no-warn disable warnings
--check-marked GC_CHECK_MARKED_OBJECTS=1
--optim no debug defines
--gprof make Emacs for profiling
--union-type define USE_LISP_UNION_TYPE (bad for GDB)
--malloc-check define GC_MALLOC_CHECK
--no-mcheck dont define GC_MCHECK
--wall compile with -Wall
--gcc3 use GCC 3.0 (30% slower compilation, slower code)
--trace-selection print traces in xselect.c
--trace-move print traces for move_it* functions
--stabs use -gstabs instead -g
Default is to compile with warnings, with -DGC_MCHECK=1, and
with -DGLYPH_DEBUG=1.
