Re: [cdt-dev] Spawner command line lenght limitations?

[Alex Chapiro <achapiro@xxxxxxx>]

Hi Michail,

It was done for Win98 compatibility reasons. It can be changed easily ( 
MAX_CMD_SIZE preprocessor macro), we do not support Win98 any more. On 
the other hand, there is still command line limitation in WinXP (32K I 
suppose). To ignore this problem in QNX IDE we just pass all parameters 
to GNU make using temporarily created file.
