Rebuilding make

Rebuilding make

[Fedin Pavel]

  Hello!

  I want to try my hands on improving 'make' performance by switching 
from fork() to spawn(). Actually, the code is already there, under 
#ifdef __EMX__, waiting to be reused. However i have some problems 
rebuilding it:
1. doc/fdl.texi and doc/make-stds.texi files are missing from the archive.
2. configure seems to incorrectly determine HAVE_DOS_PATHS as true. This 
breaks $abspath() function.

  I solved (1) by adding these files from the original UNIX archive. Of 
course i can solve (2) by tweaking config/dospaths.m4, however perhaps i 
don't know something ? How do you build make ?

  Just FYI: i have tweaked dospaths.m4 and built a working make. After 
this i successfully patched it to use spawn(). For benchmarking i used 
'all' then 'clean' targets on make's own source code.

  'clean' target runs especially faster, you see the difference with a 
naked eye. I believe in case of gcc there's disk access factor.

0m45.759s+0m7.520s => 0m31.869s+0m2.740s

Great! Can you gist the patches somewhere please?

Calm down and READ the message you received.  It surely didn't tell you
to send implied profanity to the Cygwin mailing list.

  Sorry, i don't really understand you. What do you mean under profanity 
? Is it not allowed to post patches here ?

I was referring to your "WTF ???".

I didn't say anything about not posting patches.  Of course you can post
patches.

You apparently knew that your mail was rejected as spam because you
received a bounce.  The bounce gave you information which did not tell
you to send a complaint here.

"WTF" is implied profanity.  cgf's point was that rather than complaining that
your message was rejected, you'd have better luck reading the rejection email
and follow the instructions there.

 Ah, sorry for being impolite...
 I asked only because there was no meaningful or useful information in
the bounce message. It had only one line: "Spam score is too high".
 Well, does not matter any more.
