It was to do both.  I just checked, and the latest pdftoppm does work with 
pdf 1.5 files (I keep one as a test).  It may be the DOS/Windows version 
of pdftoppm that was not updated.  It does produce very large files using 
a rather large program (1.7MB).

You can also use gs itself to convert from pdf to p?m format instead of 
pdftopnm.  See Use.htm in /usr/local/share/ghostscript.
gs -sDEVICE=pbm -o filename-%d.pbm filename.pdf
This will produce filename1.pbm filename2.pbm ....

You can make your own script called pdf2ppm (the xdpf one is pdftoppm), 
pdftopbm, pdftogm (or if you use the larger gs with more devices including 
jpeg, pdftojpeg, etc.)

I got precompiled xpdf 3.02 from www.foolabs.net/xpdf.  I repackaged it 
without the xpdf part to make it smaller and posted as 
xpdf302-noX-nogs.tgz.  (The nogs means it works without needing gs, but 
you do need to either make a gs fonts directory and symlink to the Abiword 
fonts, or edit .xpdfrc to point directly to it).

It can handle 1.5.

svgalib also works without the 2.4 kernel, but needs to have suid bit set 
to run as user.  (chmod o+s ?).  With 2.4 kernel, you can insert a module 
svgalib_helper.o instead, which works with /dev/svga*.  There were reports 
of zgv having security problems run suid.  2.4 is needed for USB storage, 
not other USB devices.

In /etc/vga libvga.config, to use kernel 2.2, comment out the line

Helper /dev/svga (I don't recall how I set it by default)

About 10MB free space, I think.  Much less than for glibc.  I was 
compiling for BL1 on a 486 (kermit).  I can't find the instructions for 
setting up to compile with BL1 or BL3 at the website but they are listed 
at https://lists.ibiblio.org/sympa/arc/baslinux/2006-June/010786.html

binutils, egcs, gmake, libc (full), linuxinc

Then download your source code, unpack it, read INSTALL (or README) in the 
main directory or sometimes in docs, if instructed to do so edit 
Makefile.cfg or some other file (or accept the defaults), ./configure (for 
most programs but some are strange), then 'make' or 'make install' 
(however you are instructed).

Which program are you after?  For dropbear (dbclient/scp) there is an 
INSTALL which says to Edit options.h to set features (you can just ignore 
this), then ./configure (optionally with --disable-zlib or 
--disable-syslog) and then make PROGRAMS="dbclient scp"  (or make them 
all). or make ....... install (installs to /usr/local/bin)

make clean before you recompile differently.

strip scp will remove stuff not needed for normal use (makes it smaller).

To compile for libc5 you should do this on a setup which does not have 
glibc on it (or learn to specify which library to compile (and let me 
know).  There may be space to compile in a 20MB loop BL3.50 (or enlarge 
it).

To make static dropbear add STATIC=1 to the Make line.  Then you can 
compile without worrying about which library is used, or whether libc5 
will work with a particular program.  If you have glibc already, you can 
also use a later gcc (2.95.3).  (Or just use what I already compiled for 
glibc).

I compiled using the standard BL1 setup with the five added packages.
