compile errors on 7.2 rc1

[coolcold at coolcold.org]

gcc -fPIC -DPIC -shared -I../include -I../lib/pcre   -Wall 
-O2 -g m_ctrace.c -o m_ctrace.so
m_ctrace.c: In function `va_ctrace':
m_ctrace.c:61: warning: value computed is not used
m_ctrace.c:62: parse error before `char'
m_ctrace.c:64: `parv' undeclared (first use in this 
function)
m_ctrace.c:64: (Each undeclared identifier is reported 
only once
m_ctrace.c:64: for each function it appears in.)
make: *** [m_ctrace.so] Error 1

What the problem can be?
gcc --version
2.96

I've removed reference to ctrace in makefile and it 
compiled ok.
On another box with debian and gcc 4.0.2 it compiles fine.
