Description of Problem:
gcc2.96 reports a parse error when gcc doesn't. This has been tested with gcc 
2.91.66 on rh6.2 and 2.96-98 on rh7.2. gcc3 compiles ok.

Version-Release number of selected component (if applicable):

2.98-98

How Reproducible:

always

Steps to Reproduce:
1wget http://www.dcs.ed.ac.uk/~chrb/gccbug_311001.tar.gz
2.tar -xzvf gccbug_311001.tar.gz; cd bug
3. gcc -c commands.i

Actual Results:

commands.c: In function `MakeFVsForChannelAccesses':
commands.c:935: parse error before `synch'
commands.c:938: `synch' undeclared (first use in this function)
commands.c:938: (Each undeclared identifier is reported only once
commands.c:938: for each function it appears in.)

Expected Results:

should have compiled -
gcc3  -c commands.i
no errors reported
