+FUNCTION
+ bfd_scan_vma
+
+DESCRIPTION
+ Converts, like strtoul, a numerical expression as a
+ string into a bfd_vma integer, and returns that integer.
+ (Though without as many bells and whistles as strtoul.)
+ The expression is assumed to be unsigned (i.e. positive).
+ If given a base, it is used as the base for conversion.
+ A base of 0 causes the function to interpret the string
+ in hex if a leading "0x" or "0X" is found, otherwise
+ in octal if a leading zero is found, otherwise in decimal.
+
+ Overflow is not detected.
