Trouble with generated header file

[Mark R Bannister]

Hi,

I hope you can help.  I've been using automake, flex and bison for 10 
years on my project without complaint.  They've worked together very 
well.  Until recently when I upgraded to OpenSuSE 12.1 which shipped 
with automake 1.11.1, flex 2.5.35 and bison 2.5.

Here is a snippet from my Makefile.am:

AM_YFLAGS = -d
PARSER_FILES = parse.y parse.h palparse.h lexer.l
libpal_la_SOURCES = $(PARSER_FILES)

In configure.in:

AC_PROG_YACC
AM_PROG_LEX

There was nothing but standard yacc/bison grammar in parse.y in the 
past, and 'parse.h' was generated just fine.  N.B. automake uses 
'ylwrap' during the build process from /usr/share/automake-1.11.

Since I moved to the newer versions, I have encountered very odd 
behaviour.  The 'parse.h' file is generated as before, but the generated 
'parse.c' file now tries to include 'y.tab.h'which doesn't exist. If I 
add the following statement to the top of 'parse.y':

%defines "parse.h"

then the generated 'parse.c' file is now correct and includes 'parse.h' 
instead, but 'parse.h' is no longer generated for me!

This is driving me crazy.  My only workaround for now has been to remove 
the '%defines' statement just to get 'parse.h' generated, then add it 
back in again so that 'parse.c' is generated correctly.

Am I doing something wrong?  Any help would be much appreciated.

Best regards,
Mark.
