* February 25, 2004
- Dan Fandrich found a flaw in the Feb 22 fix.
- Added better configure --enable-debug logic (taken from the curl configure
script). Added acinclude.m4 to the tarball.
* February 23, 2004
- Removed ares_free_errmem(), the function, the file and the man page. It was
not used and it did nothing.

dnl We create a function for detecting which compiler we use and then set as

dnl options are only used for debug-builds.

dnl This file provides local macros for packages which use specific
dnl external libraries. The public macros are:
dnl
dnl ATHENA_UTIL_COM_ERR
dnl Generates error if com_err not found.
dnl ATHENA_UTIL_SS
dnl Generates error if ss not found.
dnl ATHENA_REGEXP
dnl Sets REGEX_LIBS if rx library used; ensures POSIX
dnl regexp support.
dnl ATHENA_MOTIF
dnl Sets MOTIF_LIBS and defines HAVE_MOTIF if Motif used.
dnl ATHENA_MOTIF_REQUIRED
dnl Generates error if Motif not found.
dnl ATHENA_AFS
dnl Sets AFS_LIBS and defines HAVE_AFS if AFS used. Pass
dnl in an argument giving the desired AFS libraries;
dnl AFS_LIBS will be set to that value if AFS is found.
dnl AFS_DIR will be set to the prefix given.
dnl ATHENA_AFS_REQUIRED
dnl Generates error if AFS libraries not found. AFS_DIR
dnl will be set to the prefix given.
dnl ATHENA_KRB4
dnl Sets KRB4_LIBS and defines HAVE_KRB4 if krb4 used.
dnl ATHENA_KRB4_REQUIRED
dnl Generates error if krb4 not found. Sets KRB4_LIBS
dnl otherwise. (Special behavior because krb4 libraries
dnl may be different if using krb4 compatibility libraries
dnl from krb5.)
dnl ATHENA_KRB5
dnl Sets KRB5_LIBS and defines HAVE_KRB5 if krb5 used.
dnl ATHENA_KRB5_REQUIRED
dnl Generates error if krb5 not found.
dnl ATHENA_HESIOD
dnl Sets HESIOD_LIBS and defines HAVE_HESIOD if Hesiod
dnl used.
dnl ATHENA_HESIOD_REQUIRED
dnl Generates error if Hesiod not found.
dnl ATHENA_ARES
dnl Sets ARES_LIBS and defines HAVE_ARES if libares
dnl used.
dnl ATHENA_ARES_REQUIRED
dnl Generates error if libares not found.
dnl ATHENA_ZEPHYR
dnl Sets ZEPHYR_LIBS and defines HAVE_ZEPHYR if zephyr
dnl used.
dnl ATHENA_ZEPHYR_REQUIRED
dnl Generates error if zephyr not found.
dnl
dnl All of the macros may extend CPPFLAGS and LDFLAGS to let the
dnl compiler find the requested libraries. Put ATHENA_UTIL_COM_ERR
dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there
dnl is a com_err library in the AFS libraries which requires -lutil.
