The syntax error with (\\) was probably not-critical because setting the
"float" option is probably not required.
The actual error was not detected because no one bothered to examine the
configure script log.
There was one critical error False Detection of (xpm) {xpm] is not a Posix
standard, therefore ibm does not support it
I added the header detection error flag to fix [xpm] { haltonmsg(3296) }
As I mentioned in previous emails the majority of { Xm } headers are Motif
2.1 which IBM previously did not support
I am not sure exactly when they added this new 2.1 support in ( I am
currently using z/OS 1.10 or 11 )
Unfortunately IBM made Motif 2.1 the new default which requires using a much
higher level of c standards compliant code
Compiling with the new motif 2.1 headers generates a boat-load of errors
So I inserted the old 1.2 headers back to the front of the bus (but that does
not hide the new Xm headers )
So the configure script detected all these wonderful new Xm headers (some of
which generated compile errors ) and after I hacked the code
To fix those errors I ended up with link errors because I was not and can-not
link with the new motif 2.1 xm libs
So I added a new check to exclude the new Xm headers
Finally the configure script compile options are unique to the needs of the
configure script and should not be used for the actual build process
Therefore I added a few new lines to set the correct options to be written to
the make-file

The next challenge is to try to fix things so we can use the new 2.1 headers
and the new 2.1 libs
IBM recommends using c89 >> which uses langlvl(ansi) <<
Compiling with langlvl(ansi) seems to help a lot , but it also introduces new
problems ( you can not re-define a #define !! )

Can you please make a context diff with diff -c or diff -u ?
Otherwise there might be mistakes.
I'm glad you managed to make it work. I wonder what the existing configure
lines were for. I assume your system is more recent, I don't think these lines
have been changed for several years.
Updating the os_390.txt file would also be very helpful for z/OS users.
