1. Configure does not know about the system/architecture:

z-os:/VERSYSB/usr/local/src/tux/tcsh-6.21.00 508 > sh configure --prefix=/u/tux

trap: configure 2371: FSUM7327 signal number 13 not conventional
checking for a BSD-compatible install... ./install-sh -c
checking build system type... i370-ibm-openedition
checking host system type... i370-ibm-openedition
checking cached host tuple... ok
configure: error: Tcsh can't guess the configuration file name
for `i370-ibm-openedition' systems.
Check tcsh's `Ported' file for manual configuration instructions.

2. When making this combo similar to aix, like

  ## IBM OS/390 systems
  *-ibm-os390*|i370-ibm-openedition)

I altered the Makefile to make the compiler do what was needed:

CFLAGS = \
        -qlanglvl=extended:extc89:extc99 -qlongname -qxplink -qdll \
        -qfloat=ieee -qexportall -qhaltonmsg=3296:4108 \
        -DOEMVS -D_XOPEN_SOURCE_EXTENDED -D_ALL_SOURCE -D_SHR_ENVIRON \
        -Wc,XPLINK,dll,EXPORTALL

then the start of the failures is

$  make
c99 -c -qlanglvl=extended:extc89:extc99 -qlongname -qxplink -qdll -qfloat=ieee -qexportall -qhaltonmsg=3296:4108 -DOEMVS -D_XOPEN_SOURCE_EXTENDED -D_ALL_SOURCE -D_SHR_ENVIRON -Wc,XPLINK,dll,EXPORTALL -I. -I. -D_PATH_TCSHELL='"/u/tux/bin/tcsh"'     sh.c

Any hints or suggestions or shall I dig on myself?
