[En-Nut-Discussion] Nut/OS 4.6 build errors / Warnings

[Ernst Stippl]

Hi!
 
I ran Nut/OS 4.6 thru several gcc versions and go tht efollowing errors:

This seems to be the probleme described by Henrik Maier on Aug. 8th 2008.
The following discussion
did focus on functional issues but only once suggested to use another
version of libc to circumvent 
the compile time problem. 
----------------------------------------------------------------
To successfully compile WLANDRV.C I added 

#define GCC_VERSION (__GNUC__ * 10000  + __GNUC_MINOR__ * 100  +
__GNUC_PATCHLEVEL__)
#if GCC_VERSION >40299
#pragma GCC diagnostic ignored "-Warray-bounds"  
#endif

based on Thiago A Corrêa's mail from July 1st 2008. But is was necessary to
check for the compiler 
version because older versions did choke on the "#pragma" 
----------------------------------------------------------------

I am in the process of updating my website and will add this information.
