Hi,
I recently tried to define autoconf macros for a new language `Lang' using
[AC_DEFUN([AC_LANG_COMPILER(Lang)], [AC_REQUIRE([AC_PROG_CLANG])])
but as a consequence aclocal failed:
autom4te ... --trace='AC_LANG_COMPILER(Lang)' ...
=> /bin/sh /usr/bin/m4 ... --trace=AC_LANG_COMPILER(Lang) ...
=> /bin/sh failed with: syntax error at `(' or so.
The reason is, that the macro names passed from autom4te to M4 lack proper
shell quoting.
Attached is a small patch (against git as of today) fixing this problem,
together with a test case.
Regards
