[Bug-gnubg] Compile error on MacOS 10.5.2

[Achim Mueller]

Hi folks,

I just started with the "project" gnubg on MacOS 10.5. Here is my first
compile error:

In file included from /usr/include/sys/time.h:77,
                 from /usr/include/sys/sysctl.h:82,
                 from neuralnet.c:630:
/usr/include/sys/_structs.h: In function 'CheckSSE':
/usr/include/sys/_structs.h:192: error: nested functions are disabled,
use -fnested-functions to re-enable
/usr/include/sys/_structs.h:192: error: invalid storage class for
function '__darwin_fd_isset'
make[2]: *** [neuralnet.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Ciao
