This is a list off shell functions that appear in the generated libtool script on my linux system (one of Ralf's patches is applied). Yes, we could probably move these around some to get func_mode_compile closer to

the top.

The important thing is not how close func_mode_compile() is to the top,

but how close the code which invokes it is to the top.

Most of these optimizations are already done in 2.2.2.  The code
invoking func_mode_compile is right after its definition.

Wrt. moving functions, func_win32_libid, func_generate_dlsyms, and
func_extract_an_archive, func_extract_archives can still be moved
after func_mode_compile.  That gets another 10% overhead reduction.
My patches from last night get about the same amount.

that moves all of these functions to after mode_compile.

func_mode_help can also be easily moved, I am testing a patch currently

Pity that the following spews garbage :-(
