Bug#468775: gdc-4.1: ii-esu and projectl FTBFS on ia64: unable to find a register to spill in class 'GR_REGS'

[Peter De Wachter <pdewacht@gmail.com>]

Package: gdc-4.1
Version: 0.25-4.1.2-19
Severity: normal

projectl and ii-esu fail to compile on ia64. The errors look similar,
so I'm bundling them in one bug report.
