Adding *float + float seems to be not possible. [egcs-2.91.66]

[Michal Bartczak]

gcc version:
egcs-2.91.66
system type:
red-hat 6.0
Linux 2.2.5-15 i686 unknown (pentium II)

options for compiler:
gcc -Wall <source_name> -lm ;)

Sources included. Output is:
/*************** snip   *****************/

/* rest is not important, because bug is visible here */

how can be 22.1 + 0.01 = 22.110001 ? Accumulating error? 

This is repeatable on PowerPC egcs too :P (old egcs 1.0.2 - prerelease) 
[Linux 2.0.33 - osfmach3, ppc unknown (604)]

or maybe I'm doing something stupid. ?
