AC_SEARCH_LIBS does not clean up

Hello,
  I noticed that the "break" called in a parameter to
AC_LINK_IFELSE skips the command
        rm conftest conftest.$ac_objext ...

This means that the files are left uncleaned.

The patch attached to this mail exposes the problem.

There are two ways to fix the problem:
1) Add a "rm" to AC_SEARCH_LIBS
2) Fix the macro AC_LINK_IFELSE so that it cleans up before it executes
   the commands given as parameters.

Variant 2) seems cleaner.  If we decide for it, we also have to fix
a dozen of similar macros in autoconf/general.m4.

Which variant would the reders here prefer?

Have a nice day,
        Stepan Kasal
