[issue877121] configure detects incorrect compiler optimization

[Michael Schmarck]

Michael Schmarck <michael.schmarck at habmalnefrage.de> added the comment:

This still happens with Python 2.6b3, 3.0b3 and 2.5.2 and Sun Studio 12
on Solaris Sparc.

Like mentioned in Issue1162001, the problem seems to be, that cc returns
0 if -OPT:Olimit=0 is used:

--($ ~)-- cc  -OPT:Olimit=0 test1.c; echo $?
cc: Warning: illegal option -OPT:Olimit=0
0

--($ ~)-- gcc  -OPT:Olimit=0 test1.c; echo $?
cc1: error: invalid option argument `-OPT:Olimit=0'
1

I ran this configure:

CXX=/opt/SUNWspro/bin/CC CC=/opt/SUNWspro/bin/cc ./configure
--prefix=$HOME/.software/python-2.6b3 --disable-ipv6 --enable-shared
--without-gcc --with-threads --with-doc-strings

The prefix was always different, of course :)

--($ ~)-- gcc --version
gcc (GCC) 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
