You may define this macro to the lexical type of the @kbd{$} character. The
default value is @code{LEX_NAME | LEX_BEGIN_NAME}.
+@item NUMBERS_WITH_SUFFIX
+@cindex NUMBERS_WITH_SUFFIX
+When this macro is defined to be non-zero, the parser allows the radix of a
+constant to be indicated with a suffix. Valid suffixes are binary (B),
+octal (Q), and hexadecimal (H). Case is not significant.
+
@item SINGLE_QUOTE_STRINGS
@cindex SINGLE_QUOTE_STRINGS
If you define this macro, GAS will treat single quotes as string delimiters.
