Pat's "how to make the Slackware egcs package" notes.

To make the Slackware package, untar egcs source, configure and build 
as in egcs.configure and egcs.make.  Then, we add these items to what's
installed with a "make install", and package it up with "makepkg".

The egcs-2.1.1-linux.patch comes from the RedHat RPM, and is used 
so that we get compatible .sonames for libstdc++.  They give hjl's
directory on ftp.varesearch.com (/pub/support/hjl/) as the original
source, but I didn't find the patch there.  The source of the -davem
patch is unknown, but I suspect davem has something to do with it. ;)

1. add /usr/bin/cpp:
#!/bin/bash -
for i in /usr/lib/gcc-lib/i*86*linux*/*/cpp; do
  exec "$i" "$@"
done

2. add /lib/cpp -> /usr/bin/cpp link.

3. Adjust filenames and links in /usr/bin:
lrwxrwxrwx   1 root     root            3 Jun 22 17:58 c++ -> g++*
-rwxr-xr-x   1 root     bin         25500 Jun 22 17:35 c++filt*
lrwxrwxrwx   1 root     root            3 Jun 22 18:01 cc -> gcc*

-rwxr-xr-x   1 root     bin         13904 Jun 22 17:35 gcov*
lrwxrwxrwx   1 root     root           12 Jun 22 17:57 i386-slackware-linux-gcc -> egcs-2.91.66*
-rwxr-xr-x   1 root     bin         29984 Jun 22 17:35 protoize*

# Obsolete.  The /usr/ix86-linux/ target came from the official releases of libc5, and was never a target
# supplied by GNU software, so far as I know.  We will use /usr/i386-slackware-linux/ as the build target
# for Slackware Linux systems from now on.
#4. mv /usr/i386-pc-linux-gnulibc1 to /usr/ix86-linux.
#
#5. add i386-pc-linux-gnulibc1 -> ix86-linux link in /usr.

# Also obsolete.  Recent versions of egcs place this file (now called g2c.h) in /usr/lib/i386-*-linux/egcs-*/include,
# which seems like a good enough place for it.
#6. mv /usr/local/include/f2c.h to /usr/include/f2c.h.  rmdir empty /usr/local.

# /usr/lib/g++-include/ is another obsolete libc5 convention.  And the .so links are handled properly by egcs now.
#7. Add links in /usr/lib:
#   g++-include -> /usr/include/g++
#   libstdc++.so -> libstdc++.so.2.8

8. gzip files in /usr/info, /usr/man/man1.

9. Add links in /usr/man/man1:
   lrwxrwxrwx   c++.1.gz -> g++.1.gz
   lrwxrwxrwx   cc.1.gz -> gcc.1.gz
   lrwxrwxrwx   cpp.1.gz -> cccp.1.gz
   lrwxrwxrwx   f77.1.gz -> g77.1.gz

10.  That's about it... now add any additional documentation needed in 
     /usr/doc, and then package it up with makepkg, or split into 
     C/C++/Obj-C/F77 packages and package those up with makepkg.
