+# SYNOPSIS
+#
+# AX_RESTORE_FLAGS_WITH_PREFIX(PREFIX, LIST-OF-FLAGS)
+#
+# DESCRIPTION
+#
+# Restore the flags saved by AX_SAVE_FLAGS_WITH_PREFIX.
+#
+# Expansion example: AX_RESTORE_FLAGS_WITH_PREFIX([GL], [[CFLAGS],[LIBS]])
+# expands to
+#
+# CFLAGS="$gl_saved_flag_cflags"
+# LIBS="$gl_saved_flag_libs"
+#
+# One common use case is to define a package specific wrapper macro around
+# this one, and also restore other variables if needed. For example:
+#
+# AC_DEFUN([_AX_CHECK_GL_RESTORE_FLAGS], [
+# AX_RESTORE_FLAGS_WITH_PREFIX([GL],[$1])
+# AC_LANG_POP([C])
+# ])
+#
+# # Restores CFLAGS, LIBS and language state
+# _AX_CHECK_GL_RESTORE_FLAGS([[CFLAGS],[LIBS]])

+# SYNOPSIS
+#
+# AX_SAVE_FLAGS_WITH_PREFIX(PREFIX, LIST-OF-FLAGS)
+#
+# DESCRIPTION
+#
+# For each flag in LIST-OF-FLAGS, it expands to lower-cased shell variable
+# with the prefix holding the flag original value. The saved variables
+# can be restored by AX_RESTORE_FLAGS_WITH_PREFIX
+#
+# As an example: AX_SAVE_FLAGS_WITH_PREFIX([GL], [[CFLAGS],[LIBS]])
+# expands to
+#
+# gl_saved_flag_cflags="$CFLAGS"
+# gl_saved_flag_libs="$LIBS"
+# CFLAGS="$GL_CFLAGS $CFLAGS"
+# LIBS="$GL_LIBS $LIBS"
+#
+# One common use case is to define a package specific wrapper macro around
+# this one, and also setup other variables if needed. For example:
+#
+# AC_DEFUN([_AX_CHECK_GL_SAVE_FLAGS], [
+# AX_SAVE_FLAGS_WITH_PREFIX([GL],[$1])
+# AC_LANG_PUSH([C])
+# ])
+#
+# # pushes GL_CFLAGS and GL_LIBS to CFLAGS and LIBS
+# # also set the current language to test to C
+# _AX_CHECK_GL_SAVE_FLAGS([[CFLAGS],[LIBS]])
