Hi I am getting a compile error with 3.1.4 on IBM Power ppc64 running Red Hat Enterprise Linux AS release 4 (Nahant Update 8). The error is :- mem.cc: In function `void memConfigure()': mem.cc:359: warning: converting of negative value `-0x00000000000000001' to `size_t' src/mem.cc has a change from 3.1.3 from > new_pool_limit = mem_unlimited_size; To < new_pool_limit = -1; which seems to be the problem. Compiler is gcc version 3.4.6 20060404 (Red Hat 3.4.6-11). Thanks Steve
