Comment (by kgardas):
It seems that config.guess always is using `cc' compiler (as it is
installed) otherwise it would use gcc. i.e. cc is on the first try. The
issue is that current config.guess is buggy while invoked from bash. i.e.
code like:
{{{
if echo '\n#ifdef __amd64\nIS_64BIT_ARCH\n#endif' | \
(CCOPTS= $CC_FOR_BUILD -E - 2>/dev/null) | \
grep IS_64BIT_ARCH >/dev/null
}}}
should generate following C code:
{{{
#ifdef __amd64
IS_64BIT_ARCH
#endif
}}}
but if invoked in bash, then it generates this code:
{{{
\n#ifdef __amd64\nIS_64BIT_ARCH\n#endif
}}}
which C preprocessor leaves as it is and following grep finds IS_64BIT and
config.guess things it's detecting AMD64 platform correctly.
So yes, if I invoke config.guess from the command line, it's run by
/bin/sh and it generates correct C code and reports i386-pc-solaris2
platform. The problem is that configure seems to always run config.guess
by bash and so config.guess generates bad C code and reports x86_64
platform.
