> helo i got the macro error

Please quit starting a new thread every time you send a message.  And when
sending a file, please attach it.  By inlining your acinclude.m4, your
lines wrapped, and the line numbers no longer corresponded to your error
messages, making it harder to debug.

> acinclude.m4:36: warning: underquoted definition of AC_FIND_FILE

The actual bug is located within the K_PATH_X macro.  Please report it
along with all these warnings of underquoted definitions, to the KDE
libraries/packages maintainers - the maintainers should fix their macros
to use proper quoting.  You have not uncovered any autoconf bugs.

This line closes the AC_DEFUN of K_PATH_X...

> 
> AC_LANG_RESTORE

Meaning that this line is executed in isolation at the top level, without
a matching AC_LANG_SAVE.  Too many close quotes somewhere in the macro
definition.
