Hi Bob,

Everything would be easier if libtool would arrange to build a small helper
executable in the build tree which it can used instead of system tools.
Libtool already builds a native executable in some cases. This would
diminish portability concerns and improve performance.  The main issue
with this is that for cross-builds, a system native compiler needs to be
used to build the helper executable.

Forgive me for my ignorance, but when does libtool build something with
the $build compiler in the cross case? The only thing I can find that
looks like an alternative compiler is $LTCC, but that's just another
name for the normal $host C compiler. What am I missing?

As I recall, libtool builds an execution test wrapper for a Windows native build. It would (should) not do that for a cross-build. However, the C test wrapper was written using portable interfaces so it could compile under POSIX (even if we don't currently do that).

In windows case I would like to disagree. this is a way to run test in emulated environment. Build system run in emulator a native executable (libtool wrapper executable) , then wrapper set environment and spawn real executable. This is specific for this case and know emulator. I would like to inform you that shell-wrapper from pre-libtool 2(.2?) era can not be used in this case.
May be I misunderstand you idea .
Please detail you case.
