15dnl This file provides local macros for packages which use POSIX
16dnl regexp support.  The public macros are:
17dnl     ATHENA_REGEXP
18dnl             Sets REGEX_LIBS if rx library used; ensures POSIX
19dnl             regexp support.
20dnl
21dnl All of the macros may extend CPPFLAGS and LDFLAGS to let the
22dnl compiler find the requested libraries.  Put ATHENA_UTIL_COM_ERR
23dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there
24dnl is a com_err library in the AFS libraries which requires -lutil.
