Description of problem:

During imake run on ppc64 platform I get recursion error:

xmkmf
imake -DUseInstalled -I/usr/share/X11/config
In file included from /usr/share/X11/config/Imake.tmpl:2194:0,

Version-Release number of selected component (if applicable):
1.0.7-7.fc26

How reproducible:
Foto rasmol sources, run it as above.

Additional info:
Works fine on x86_64/arm.

This is related to:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/PANPXK43S24TMUGLZ667NPAGNTZKMC6L/

So the keyword "vector" or so is somewhat special with GCC on ppc64{,le}. Usually you have to use "gcc -std=gnu11" or so or explicitly use "#undef vector" when this issue occurs on ppc64.

Unfortunately, for this case, xmkmf -> imake calls "cpp" internally with some option, so you have to modify either compiler flags being passed to cpp, or change _some_ code (perhaps template file used by imake) to explicitly undef vector... but imake internal looks a bit complicated.

For now the following seems to work:

Looks like imake_defines= in xmkmf would be a good place for -Uvector.

Thanks. Didn't guess to look into xmkmf.

No way to place it there. Only '-D' args parse and they placed as is, with '-D'. Option named "-DUvector" is not what I need here.
Anyway, this script do nothing but generate command posted in #1. I believe I could run it manually as suggested.

Thanks for help!
