------- Comment #13 from davek at gcc dot gnu dot org 2009-07-26 14:26 -------
Broken again on HEAD :-(
Configured with --program-suffix=-4, bootstrapped, and installed into a new
$prefix that I then placed at the front of $PATH.
None of the newly built gnat* executables had the --program-suffix appended.
When trying to run the testsuite, host_gnatmake invokes plain unadorned
'gnatmake', which finds the newly-installed one in $prefix. That attempts to
invoke plain unadorned 'gcc' unfortunately, which is the distro compiler
installed in /usr/bin, and not the newly installed $prefix/bin/gcc-4, resulting
in the following error:
> + host_gnatmake -gnatws macrosub.adb

> gcc -c -gnatV -gnatws macrosub.adb
> gnat1: invalid switch: -gnatea
> End of compilation
I tried hacking host_gnatmake and host_gnatchop to pass --GCC=gcc-4, but that
only got me a little way further:

... the problem being that yet again the unsuffixed system compiler has been
invoked, and it's using the system runtime libs rather than the ones that go
with the newly-built compiler in $prefix (and which happen to be ABI
incompatible because they use ZCX instead of SJLJ).
Should gnatmake have passed down the --GCC= option to gnatbind and gnatlink?
