regex+old_include on gcc 3.2

Hi all, I am using regex library compiled using gcc 3.2 and with the old_include header files. I wrote this code a year ago. While compiling it gives following error.. /boost/old_include/regex.h:410: `jm_def_alloc' not declared /boost/old_include/regex.h:412: `re_alloc_binder' not declared /boost/old_include/regex.h:443: `jm_def_alloc' not declared any ideas.. thanks sandeep
