Compile error on Gentoo Linux: warning: ignoring return value of 'size_t fwrite(const void*, size_t, size_t, FILE*)', declared with attribute warn_unused_result

[Christian van der Leeden]

MongoVersion: 1.6.0
g++ (Gentoo 4.3.4 p1.0, pie-10.1.5) 4.3.4


When compiling on Linux (Gentoo) I get an error saying that:
ignoring return value of 'size_t fwrite(const void*, size_t, size_t,
FILE*)', declared with attribute warn_unused_result

This error/warning is already in 1.5.x but there it is not reported as
error,

Fix:
remove the -Werror flag from SConstruct which will abort the compile
(or fix the problem of the warning in the first place)

Christian
