[Bug libgomp/36475] New: [gomp] register keyword in openmp handled for-loop fails

["Klaas dot Vantournhout at UGent dot be" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

Using the register keyword in a for loop which is handled by OpenMP fails to
compile.

Testcase below

g++ -v
Using built-in specs.
Target: x86_64-manbo-linux-gnu
Configured with: ../configure --prefix=/usr --libexecdir=/usr/lib
--with-slibdir=/lib64 --mandir=/usr/share/man --infodir=/usr/share/info
--enable-checking=release
--enable-languages=c,c++,ada,fortran,objc,obj-c++,java
--host=x86_64-manbo-linux-gnu --with-cpu=generic --with-system-zlib
--enable-threads=posix --enable-shared --enable-long-long --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-clocale=gnu --enable-java-awt=gtk
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --enable-gtk-cairo
--disable-libjava-multilib --enable-ssp --disable-libssp
Thread model: posix
gcc version 4.2.3 (4.2.3-6mnb1)

===== test code =====
#include <omp.h>

int main() {
#pragma omp parallel for
  for (register int i = 0; i < 2; ++i) {
  }
  return 0;
}
====== compilation output ====
 g++ -fopenmp register.c
register.c: In function ?int main()?:
