dnl Useful macros for autoconf to check for ssp-patched gcc
dnl 1.0 - September 2003 - Tiago Sousa <mirage@kaotik.org>
dnl 1.1 - August 2006 - Ted Percival <ted@midg3t.net>
dnl * Stricter language checking (C or C++)
dnl * Adds GCC_STACK_PROTECT_LIB to add -lssp to LDFLAGS as necessary
dnl * Caches all results
dnl * Uses macros to ensure correct ouput in quiet/silent mode
dnl 1.2 - April 2007 - Ted Percival <ted@midg3t.net>
dnl * Added GCC_STACK_PROTECTOR macro for simpler (one-line) invocation
dnl * GCC_STACK_PROTECT_LIB now adds -lssp to LIBS rather than LDFLAGS
dnl
dnl About ssp:
dnl GCC extension for protecting applications from stack-smashing attacks
dnl http://www.research.ibm.com/trl/projects/security/ssp/
dnl
dnl Usage:
dnl Most people will simply call GCC_STACK_PROTECTOR.
dnl If you only use one of C or C++, you can save time by only calling the
dnl macro appropriate for that language. In that case you should also call
dnl GCC_STACK_PROTECT_LIB first.
dnl
dnl GCC_STACK_PROTECTOR
dnl Tries to turn on stack protection for C and C++ by calling the following
dnl three macros with the right languages.
dnl
dnl GCC_STACK_PROTECT_CC
dnl checks -fstack-protector with the C compiler, if it exists then updates
dnl CFLAGS and defines ENABLE_SSP_CC
dnl
dnl GCC_STACK_PROTECT_CXX
dnl checks -fstack-protector with the C++ compiler, if it exists then updates
dnl CXXFLAGS and defines ENABLE_SSP_CXX
dnl
dnl GCC_STACK_PROTECT_LIB
dnl adds -lssp to LIBS if it is available
dnl ssp is usually provided as part of libc, but was previously a separate lib
dnl It does not hurt to add -lssp even if libc provides SSP - in that case
dnl libssp will simply be ignored.
