parse error in gcc 3.2 with bison 1.875

[sigbert]

Hi,

it seems I have a problem with bison 1.875 and gcc 3.2. If I compile my y.tab.c 
file I get the 
error message:

g++ -c -x c++ y.tab.c
y.tab.c: In function `int yyparse()':
y.tab.c:1548: parse error before `goto'
make: *** [skwin] Error 1

This happens under Cygwin & MinGW as well as under Solaris 2.8. It does not 
happen 
under MinGW 2.95.3 & bison 1.35. If uncomment the line

  __attribute__ ((__unused__))

then y.tab.c compiles also under gcc 3.2.
