Hi!

I'am trying to figure out why the c++ code generation via bison failed. I'am
using bison 2.1 and the m4 1.4.9. I try to call:

bison -d -v --skeleton=lalr1.cc InputParser.yacc

and get the error:

E:\work\Programmierung\Compiler\FlexBison\ToolChain>bison -d
-v --skeleton=lalr1
.cc InputParser.yacc
m4:C:/PROGRA~1/GnuWin32/share/bison/lalr1.cc:22: cannot open
`c:/progra~1/Bison/
share/bison/c++.m4': No such file or directory
bison: untergeordnetes Programm äm4ô fehlgeschlagen (R³ckgabewert 1)

The c++.m4 file is at C:\Programme\GnuWin32\share\bison. So why complain?

I'am using a batch file for that. As you can see there are some problems with
the char set. Maybee this can be the error.

I also suddied a litle bit the m4 manual and set the M4PATH enviroment value
to "C:\Programme\GnuWin32\share\bison".

Thanks!

Stefan
