Hi All

  For all that followed the thread about replacing this UNIX sequence: I 
finally used the ANSI solution (system) and it worked perfectly under DOS and 
Linux. But to my surprise the author of SDCC altered my patch! I did it very 
carefully to avoid adding even a single line djgpp dependant and he filled 
the code with #ifdef __DJGPP__. So I asked why.
 He told me that some Win32 users (there are a CygWin port) reported that the 
system solution fails! 
 Sandeep (author of SDCC) failed to understand why exactly but looks like 
people running CygWin programs that uses system *must* have a valid sh in the 
path. It looks very strange because according to a post in the Allegro 
mailing list (problems with makefiles for CygWin) looks like Make uses 
command.com if no shell is available, but perhaps that's made by code in Make 
and no automatically by system.
 Anybody knows about it? Eli, you know about make, what's your opinion? DJ, 
you know about Cygnus tools, what's the problem?
 I told Sandeep that Cygnus people should consider including a shell in the 
.zip in the same way they are including cywin.dll and I'm including 
cwsdpmi.exe. But if it is too much asking I will finally forced to write a 
spawn equivalent using fork/exec/wait for UNIX and CygWin.
