QNX's version is fine, but Configure +# will choke on the 16-bit version, so if you are +# running QNX 4.22, link /bin/sh to /bin32/ksh +# ar This is the standard unix library builder. +# We use wlib. With Watcom 10.6, when wlib is +# linked as "ar", it behaves like ar and all is +# fine. Under 9.5, a cover is required. One is +# included in ../qnx +# nm This is used (optionally) by configure to list +# the contents of libraries. I will generate +# a cover function on the fly in the UU directory. +# cpp Configure and perl need a way to invoke a C +# preprocessor. I have created a simple cover +# for cc which does the right thing. Without this, +# Configure will create it's own wrapper which works, +# but it doesn't handle some of the command line arguments +# that perl will throw at it. +# make You really need GNU make to compile this.
