Latest (August) gcc update broke precompiled headers again?

I'm using precompiled hearders with gcc 3.3 as described here:

http://www.cocoadev.com/ index.pl?UsingPCHWithGCCThreeThreeAndProjectBuilder

However, since I updated to the August version, when I get to the main part of my compile I see:

CompileC <snip>/Unicode Font Info/build/Unicode Font Info.build/UnicodeFontInfo.build/Objects-normal/ppc/CharacterMatrix.o
/usr/bin/gcc-3.3 -c -F"<snip> Unicode Font Info/build" -I"<snip>/Unicode Font Info/build/include" -Iclasses -arch ppc -fno-common -fpascal-strings -O0 -Winvalid-pch -Wmost -Wno-four-char-constants -Wno-unknown-pragmas -pipe "-fmessage-length=0" -mdynamic-no-pic -g -precomp-trustfile "<snip>/Unicode Font Info/build/Unicode Font Info.build/UnicodeFontInfo.build/TrustedPrecomps.txt" "-Wp,-header-mapfile, <snip>/Unicode Font Info/build/Unicode Font Info.build/UnicodeFontInfo.build/Unicode Font Info.hmap" -include ufi_Prefix.h "-DMAC_OS_X_VERSION_MIN_REQUIRED=1020" classes/CharacterMatrix.m -o "<snip>/Unicode Font Info/build/Unicode Font Info.build/UnicodeFontInfo.build/Objects-normal/ppc/CharacterMatrix.o"
<command line>:1078300242:16453: warning: ./ufi_Prefix.h.gch: not for GNU Objective-C

What does "-precomp-trustfile" do?

Judging by the compilation speed, my pre-compiled headers are being ignored again. Anyone know to fix?
