Bug#548960: fails to build with newer eglibc (local definition of round)

[Stefan Potyra <sistpoty@ubuntu.com>]

Package: fbb
Version: 7.04j-8
Severity: normal
Tags: patch

Hi,

thanks for maintaining fbb.

During Ubuntu's rebuild test, fbb failed to build with gcc-4.4 in conjunction
with a newer eglibc [1].

The reason is that eglibc nowadays defines round (as per C99).

A simple fix is to simply use round from <math.h>, eradicating the local
definition. Probably better is to check for round with feature_test_macros.

The attached patch simply removes the local definition. Admitted, I haven't 
checked if this does build on unstable yet :(.

Cheers,
    Stefan.
