Hi there,
I have a problem compiling the following parser with gcc-3.3 in a 64 bit
environment: the compiler consumes a lot of cpu time, but never returns.
On my old 32 bit box I could compile a similar parser without problems. Also I
can compile this parser with gcc-3.3 -m32. With gcc-4.1 I can build a 64 bit
version but due to company restrictions I have to use the gcc-3.3.
Thanks for any suggestions.
Jörg
