[bug-gnu-libiconv] "cp1255.h", line 99: warning: nonportable bit-field type

[Dennis Clarke]

Not sure if the qualifies as a bug but it seems to be a valid warning. 

Here are all the details I have on hand : 

Solaris 10 Sparc server thus : 


$ uname -a 
SunOS ceres 5.10 Generic_144488-11 sun4u sparc SUNW,Sun-Fire-480R

$ psrinfo -pv 
The physical processor has 1 virtual processor (0)
  UltraSPARC-III+ (portid 0 impl 0x15 ver 0x23 clock 900 MHz)
The physical processor has 1 virtual processor (1)
  UltraSPARC-III+ (portid 1 impl 0x15 ver 0x23 clock 900 MHz)

The physical processor has 1 virtual processor (3)
  UltraSPARC-III+ (portid 3 impl 0x15 ver 0x23 clock 900 MHz)
 
$ fpversion 
 A SPARC-based CPU is available.
 Kernel says CPU's clock rate is 900.0 MHz.
 Kernel says main memory's clock rate is 150.0 MHz.

 Sun-4 floating-point controller version 0 found.
 An UltraSPARC chip is available.

 Use "-xtarget=ultra3cu -xcache=64/32/4:8192/512/2" code-generation option.
