Jon Trulson 2b8803a8fb configure: Several changes related to locating cpp and ksh ... For ksh, we need a full pathname. AC_CHECK_PROGS only sets the name, so we can't use that (think of a "#!" in a shell script. We use some shell scripting to locate the ksh pathname. While on that subject, the current use of CPP (gcc -E) as a general preprocessor does not work very well. I messes up whitespace, adds/translates random whitespace, and complains bitterly about single quotes (') in various places like comments. It's not usable for what CDE needs. So, now we use GENCPP. Using shell scripting like that used for ksh, we locate the cpp program, and set GENCPP to "/full/path/to/cpp -traditional -nostdinc". This is what Linux uses now in an Imake build, and it works fine. We'll have to see what the BSD/Solari do. We might need to just include BSD's "tradcpp" into the build and use that. It too works well in limited testing, but eats blank lines. We can live with that if we have to.		2019-10-30 17:42:31 -06:00
