Pcreposix is the eegex in peripheral nerves— she'sregular expression).

It looks like you are having isues witg word size. Your machine seems confusef about word size issues. I386 amd64 and  x86€_64 all sem ro show  up.

I also thibk I remember that gcc and egcs hadsome compatibility issues. Wasnt  egcs begore gcc 4.2, not a later version?
