NEED LINUX/ELF GPC (only a TRY to help you ...)_(re)

According to Arcadio Alivio Sincero:

If you really want to try to implement this yourself, I suggest the
following strategy:

  - get GCC 2.6.3 and GCC 2.7.0 source,
  - look, which files of the GPC 2.6.3 source are replacing GCC 2.6.3
    files, and make diffs between GCC 2.6.3 and GPC 2.6.3 for them,
  - do the GPC changes to the GCC 2.7.0 files,
  - compile GCC 2.7.0 (one stage is enough),
  - compile GPC, now version 2.7.0, and hope the best,
  - send your files to Juki, because he will be interested,
  - send your files to me, because I am interested, too.

Since I expect trouble when doing this, let us first try it in another way ...

Which gcclib do you use?  Perhaps it is already the 2.7.0 version while
crt0.o and gpc expect the 2.6.3 version.  I suggest to install the com-
plete gcc 2.6.3 in /usr/bin and /usr/lib.  (It should work with SlackWare
3.0, as I hope.)  Then also install gpc 2.6.3, and they should work to-
gether.

This gives hope to me, that the above idea could work.

For case of emergency I will figure out how to run GPC under EMX in the
DOS emulator of Linux.  This is somehow stupid, but should work.

Till later,
