Re: Compiling and linking problems

 Dear Mike,

The config.h you provided looks correct. Until we find a more permanent
solution, you have two options:
a) run configure with --disable-reentrant, or
b) follow Heinrich's solution

This has been discussed in the past[1] and Andrew seems to favour option a.

Best Regards,

Chris Matrakidis
