First of all, this looks like a major problem: looking at
regressiong tests result for linux, I see that filesystem tests fail for
that reason, and some other too -- 53% of tests fail.

Further, I can't understand the following part of regression logs:

operations_test / gcc
[snip]
     /opt/gcc2/bin//g++  -c -Wall -ftemplate-depth-100   -g -O0 -fno-inline 
-I"../libs/filesystem/test"  -I "/home/boost/boost-regress/boost"  -o 
"../libs/filesystem/test/bin/operations_test.test/gcc/debug/runtime-link-dynamic/operations_test.o" 
  "/home/boost/boost-regress/boost/libs/filesystem/test/operations_test.cpp"

operations_test / gcc2953
[snip]

Compiler output:
[snip]
     /opt/gcc2/bin//g++  -c -Wall -ftemplate-depth-100   -g -O0 -fno-inline 
-I"../libs/filesystem/test"  -I "/home/boost/boost-regress/boost"  -o 
"../libs/filesystem/test/bin/operations_test.test/gcc2953/debug/runtime-link-dynamic/operations_test.o" 
  "/home/boost/boost-regress/boost/libs/filesystem/test/operations_test.cpp"

Is the same compiler invoked in both cases? This is very likely, because I've
just build filesystem library with gcc3.2/Boost.Build2 without problems.

BTW, Gabriel, why you say about "pretty-printing"? I though no
RTL is pretty printed in default gcc settings...
