qcc/QCC with "-pipe" option produce error on QNX 6.4.1   
If I use a simple Makefile that was working on previous version of QNX (6.21, 6.3, 6.40) I got the following error with 
QNX 6.4.1:
  
--------------  
  $ qcc -O2 -Wall -g -pipe -I. -c -o somefile.o somefile.c
  cc1: error: unrecognized command line option "-pipe"
  cc: /usr/qnx641/host/qnx6/x86/usr/lib/gcc/i386-pc-nto-qnx640/4.3.3/cc1 error 1
--------------

If I use directly gcc instead of qcc, it work.

I know that "-pipe" is probably by default and there's only the "-nopipe" option documented for qcc, but gcc take "-pipe
" and the previous version of qcc was working as well, removing the "-pipe" option to qcc can break some old Makefile...


thanks

qcc always just passed the -pipe straight through to cc1 - that is what changed (4.2.4 to 4.3.3), so it was just 
coincidence that it worked.

What coincidence you talk about.. if qcc was passing the "-pipe" to gcc before and since 4.3.3 it doesn't, it not a 
coincidence if now it doen't work and before it was working... it's just broken now..

gcc 4.3.3 support the option, it's just qcc that see the "-pipe" as a bad parameter instead of passing it to gcc...

qcc just passes -p* through to cc1, so if you did qcc -pfoobar then cc1 would see -pfoobar.

qcc only understands -nopipe, since -pipe is the default.

Sorry.. I just realize that qcc pass to cc1 and not directly to gcc..  To this qcc that don't pass "-pipe" to cc1 do the
 job for now..

qcc used to do special handling for -pipe and -pedantic. Every other -p 
option was treated as profiling. -pipe is now passed through and cc1
doesn't accept it. I'll file a PR.

The attached qcc will not pass -pipe through to cc1.
