jdk-1.4 on 5.1-current

[Jens Rehsack]

Hi all,

as all others I have problems getting jdk-1.4 compiled under -current.
The preprocessor problems I could solve on my own, but later in the 
progress I'm getting a bus error with a core dump.

It seems, the patchset is adding a flag "-O3" which is known to be
broken in all gcc3 variants, eg.:
- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11319
- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11741

My questions are:
1) How can I enable the output of the compile instruction
    which is executed (how can I enable verbose_echo)?
2) How can I modify the c/c++-compiler flags which are used
    to build java?

Thanks in advance,
Jens
