Severe problems running the libstdc++ test suite on the gcc 3.0branch

[Peter Schmid <schmid at snake dot iap dot physik dot tu-darmstadt dot de>]

I cannot run the libstdc++ testsuite after a checkout of the CVS
sources this afternoon, since the g++ compiler does not find the
required header files. Therefore, all tests fail because there are no
executables generated.  
E.g.:
WARNING: 17_intro/header_cassert.cc compilation failed to produce executable

The header files from libstdc++ are located one level above than
specified in the variable SRC_DIR in testsuite_flags. 

If I replace SRC_DIR= ../../../gcc/libstdc++-v3 by
SRC_DIR=../../../../gcc/libstdc++-v3 in testsuite_flags, the test
suite does work. I know that testsuite_flags is a generated file, but
I have no knowledge of the configure machinery, therefore I do not
know how to fix that problem. All I can glean from testsuite_flags.in,
is that the substitution of SRC_DIR=@glibcpp_srcdir@ seems to go
wrong. Is replacing SRCDIR with SRC_DIR=../@glibcpp_srcdir@ a viable
solution? 
 
Hope this helps,
Peter Schmid
