+ * read.c (eval): eval() was not fully reentrant, because the
+ collapsed buffer was static. Change it to be an automatic
+ variable so that eval() can be invoked recursively.
+ Fixes bug # 2238.
+ (eval): Apply patch # 1022: fix memory reference error on long
+ target-specific variable lines.
+ Patch provided by Steve Brown <Steve.Brown@macquarie.com>.
+
* function.c (check_numeric): Combine the is_numeric() function
into this function, since it's only called from one place.
Constify this function. Have it print the incorrect string in the
