[Bug c/40418] New: OpenMP: "collapse" clause in for-statement causes gcc to abort with an error

[frederik dot moellers at gmx dot de]

The "collapse" clause of OpenMP causes the GCC to abort the compilation with an
error. The output of gcc is:

omp-matrix.c:51: error: expected ‘#pragma omp’ clause before ‘collapse’

Since the program included code written by myself, I searched for an example
program online and found one in a wiki on the Sun website which causes the same
problem:

Please note that this is my first bug report for GCC, so I want to apologize in
advance for any mistake :)
