[kaffe] [PATCH] make Double parse doubles from long strings

[Noa Resare]

When investigating a regression in BigDecimal i found out that
java.lang.Double truncates strings that it tries to parse to MAXNUMLEN
(defined to 64 in include/defs.h) before parsing it to a double.

The attached patch makes the java-string to c-string conversion be made
onto dynamically allocated memory.

If someone wonders why this is important it is because the test
((new BigDecimal("1e1000")).doubleValue))==Double.POSITIVE_INFINITY
fails. It turns out that BigDecimal.doubleValue() is implemented by
sending BigDecimal.toString() to Double.parseDouble(). Of course
BigDecimal.toString() returns a string 1000 chars long.


Please apply.

/noa

ps. the mauve regressions when comparing 1.1.4 to HEAD cvs is steadily
shrinking. Now down to 6 uninvestigated.
