Re: Multiple commands in one 'actions' group

Ok, well there is this code in the same file (basically i've just 
modified gcc.jam):

if [ os.name ] = NT
{
# This causes single-line command invocation to not go through
# .bat files, thus avoiding command-line length limitations
JAMSHELL = % ; 
}

However, removing this results in a command-line length error (>2047 
characters). Is there any way around this? Thanks.
