Well, in this case I think you have to look inside the Configure script
of Perl, there for code around the string "Checking for GNU cc in
disguise and/or its version number" and try this code manually on the
command-line to make sure that it still fails. If it's a piece of C
code, compile it with "gcc -g" (debug symbols enabled) and run it with
"gdb" and once it segfaults run "bt". The output of the "bt" command
usually gives us at least a hint where the problem migth be. It could be
also that the vendor GCC has some optimizer problems. In this case try
to compile the piece of C code with and without -O0.
