Reproducible: Always
Steps to Reproduce:
1. emerge pm3
2.
3.

Actual Results:  
it failed again, same thing
I also tried it with CFLAGS=" " and it still did not work

Expected Results:  
I was hoping it'd install...

way to steal my bug :) ... i'm also looking at cm3 since its been updated
recently ...

thank god! i was going to have nightmares about assembly :)

could you guys try out 1.1.15-r1 ?  i added a patch to hopefully fix this ...
tell me how it goes so i can close this bug ;)

http://cvs.gentoo.org/cgi-bin/viewcvs.cgi/gentoo-x86/dev-lang/pm3/files/1.1.15-errno.patch?rev=1.1&content-type=text/vnd.viewcvs-markup

I rsynced and tried emerging it and I still get the same errors... :( 

would you try out dev-lang/cm3 ?
it is another m3 compiler and it should not have the errno problem ...

i talked to the dev's upstream and they fixed errno in their cvs, they just havent made a release ...
ill see what i can do ...

I tried building cm3, and after a while I get this error:

 *** execution of  failed *** 
 
!!! ERROR: dev-lang/cm3-5.2.4 failed.

ok, so latest cm3 has errno issues too ;)

again ... the cvs version is fixed ... bleh

This really is a problem with glibc.  This entry in the RH bug tracker puts out
the issues:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=90002

its not a glibc error really ... 
 
its an error with people who used glibc incorrectly ;) 

cm3 5.2.6 is now in portage ... it has all the errno fixes ...
i'd suggest using that for now since pm3 probably wont be releasing the next
ver for some time ...

ive been talking to the cm3 maintainer and he's been actively working on cm3 so
i'd support that over pm3 for now

i installed 2 scripts in addition to cm3 (m3build and m3ship) so as to support
older packages that expect them.  they're really just running `cm3 -build ${@}`
and `cm3 -ship ${@}` ;)

alright, we got cm3 in portage ... it works fine (afaik) as a replacement for
pm3 ...

pm3 will be updated whenever the upstream guys get around to making a release
... but i wont bother back porting cvs to 1.1.5 since cvs has changed so very
radically
