Hi,
not a bug, but I don't know where to send this.
We have successfully compiled gmake on the Posix subsystem of Fujitsu-Siemens
BS2000 mainframes. Problem is that it is pretty slow, since the concept of
fork and exec is foreign to this system. They are emulated in a very costly
manner.
Since even on Unix these calls don't come for free either, I'd like to suggest
that you take up the concept of Perl's system function. That scans the string
passed for shell meta-characters and, if none are found, splits it up on
whitespace and executes the command itself.
As make is mostly about starting commands, this should give a measurable
optimization for big projects even on Unix.
best regards
Daniel
