Hmm...
script
----8X----------------------------------
#!/bin/sh -
#
rm *.gch
echo !!! Compile without gch
g++ -ansi -Werror -pedantic -Winvalid-pch -o test.o -c test.cc
echo !!! GCH generation
g++ -ansi -Werror -pedantic -Winvalid-pch -o test.h.gch -c test.h
echo !!! Compile with gch
g++ -ansi -Werror -pedantic -Winvalid-pch -o test.o -c test.cc

----X8----------------------------------
generate for me output:

rm: *.gch: No such file or directory
!!! Compile without gch
!!! GCH generation
!!! Compile with gch
test.cc:432:2: anonymous variadic macros were introduced in C99

May be this is platform specific case (FreeBSD 4.7)
I also don't link file position in my case.
I compile many my programs with same options and first recive this warning
only with PCH.
