AM_LFLAGS = --header-file=lang.h --yyclass=Lang --c++

My problem is that the file generated by lex is lex.yy.cc and not lex.yy.c.

So this command in the generated Makefile:
.lpp.cpp:
    $(AM_V_LEX)$(am__skiplex) $(SHELL) $(YLWRAP) $< $(LEX_OUTPUT_ROOT).c $@ -- $(LEXCOMPILE)

turns my lang.lpp to lang.cppc

I have looked in the ylwrap by launching it with $(SHELL) -x and had this printed
++ printf '%s\n' lex.yy.cc
++ sed 's|lex\.yy\.c|lang.cpp|g;'
+ to=lang.cppc

Am I doing it worng or is this a bug?

Thanks.
