>Release:        automake-1.7.2
>Organization:
>Environment:
Mandrake 9.0
autoconf 2.54
gcc 3.2
bison 1.35
>Description:
The order of declaration seems to be important for the _SOURCES primary when using yacc/bison. The problematic circumstances are when a c file includes the generated parser header file.

I played around with EXTRA_foo_foo_SOURCES but it made no difference.

May I suggest a bit more detail in the 'Lex and Yacc support' section in the automake manual with regard to YFLAGS=-d. For example should the generated files be placed into the EXTRA_whatever_SOURCES and whether dependencies will work.
>How-To-Repeat:
Run test case. The test case was based on yacc8.test. The output on my machine was:

>Fix:
Sorry, I was not able to fix it. There is a work around. The .y file must appear before the .c file in the _SOURCES primary.
