Hi,
This morning I configured mach/mig on
i386-unknown-freebsd4.7 machine type and it seem's to
work. (at least I got migcom installed on
$prefix/libexec...)
However, I cannot configure Hurd for the moment
because of the following line (~1631) in configure:
AC_TRY_COMPILER(main(){return(0);},
ac_cv_prog_cc_works, ac_cv_prog_cc_cross)
...
By tracing autoconf, I noticed the following
ambiguities between AC_TRY_COMPILER and
AC_TRY_COMPILE) :
autoconf: running autom4te -v -d --language=autoconf
--output=- --trace=AC_TRY_COMPILER configur
e.in
autom4te: formatting traces for
`/tmp/t4dEjzDb/dependencies': include, m4_include
autom4te: up_to_date (autom4te.cache/traces.0): up to
date
autom4te: the trace request object is:
$VAR1 = bless( [
'0',
1,
[
'/usr/local/share/autoconf'
],

# here's my bug : actually I ignore if
'AC_TRY_COMPILER' is meant to be use instead of

failing because of crossgcc 'insanity' :-)
That said, I can't find AC_TRY_COMPILER somewhere
