            Bug ID: 70660
           Summary: Autoconf problem when specifying --disable-tools
           Product: classpath
           Version: 0.99
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: classpath
          Assignee: unassigned at gcc dot gnu.org
          Reporter: guillerodriguez.dev at gmail dot com
  Target Milestone: ---

There seems to be some problem with the autoconf macros in classpath-0.99 which
was not present in 0.98. Looks like passing --disable-tools to configure also
disables the javac detection code, resulting in the following error:

===
$ ./configure --disable-tools
[...]
checking whether javac supports -J... ./configure: line 24943:
-J-Xmx768M: command not found
no
configure: error: conditional "GCJ_JAVAC" was never defined.
Usually this means the macro was only invoked conditionally
===

Note that this didn't happen in 0.98 (just re-checked) so it is probably due to
autoconf changes between 0.98 and 0.99.
