emx and its successor is the libc that is used by the OS/2 port of gcc. AFAIK,
it's basically the only compiler that can handle autoconf/automake-generated
configure scripts if this answers your question.
However, I thought that this behaviour of system() was common on DOS/Win*/OS/2
systems. At least I also checked MS VC++ on WinXP. Their docs say
-----------------------------------
system()
Execute a command.
int system(
const char *command
);
[...]
Return Value
If command is NULL and the command interpreter is found, returns a nonzero
value. If the command interpreter is not found, returns 0 and sets errno to
ENOENT. If command is not NULL, system returns the value that is returned
by the command interpreter. It returns the value 0 only if the command
interpreter returns the value 0. A return value of - 1 indicates an error,
and errno is set to one of the following values:
[...]
-----------------------------
system("xcopy non_existing_file") returns 1 for example.
Possibly, djgpp for DOS or the MinGW environment for Win* might have
the same behaviour which I cannot test because I don't use them.
