Yes, this works. But in the documentation (current CVS) for
AC_TRY_LINK I did not see a note saying that it was obsolete or that
AC_LINK_IFELSE is preferred. There is a note that says
Same as `AC_LINK_IFELSE([AC_LANG_PROGRAM([[INCLUDES]],
[[FUNCTION-BODY]])], [ACTION-IF-TRUE], [ACTION-IF-FALSE])' (*note
Running the Compiler::).
which would lead me to believe that AC_TRY_LINK is just a more concise
form of AC_LINK_IFELSE because it handles the detail of
AC_LANG_PROGRAM.
OTOH, it does say (twice)
This macro double quotes both INCLUDES and FUNCTION-BODY.
so I suppose that should have been a clue to me that the behavior I
saw should be expected.
Thanks,
