Hmmm, test:

----------8<----------
robert at callisto:~/tmp/luke ! ./test
robert at callisto:~/tmp/luke ! /usr/i386-linux-uclibc/bin/gcc test.c -o
test.o
test.c: In function `main':
test.c:5: `siginfo_t' undeclared (first use in this function)
test.c:5: (Each undeclared identifier is reported only once
test.c:5: for each function it appears in.)
test.c:5: `sigInfo' undeclared (first use in this function)
robert at callisto:~/tmp/luke ! cd
robert at callisto:~ ! cd embedded/cvs/uClibc

So siginfo_t seems not to be defined. Let's look where it comes from:

----------8<----------
robert at callisto:~/tmp/luke ! find /usr/i386-linux-uclibc/include/ \
  -name "*.h" |xargs grep siginfo_t
[...]
/usr/i386-linux-uclibc/include/asm/siginfo.h:} siginfo_t;
[...]
---------->8----------

If I use #include <asm/siginfo.h> instead of your signal.h your example
compiles just fine here.

HTH,
Robert
