BF failure - kookaburra - ecpg

One of the new ecpg tests for comments fails to compile the resulting .c
file, because my vendor C compiler doesn't like '//' style comments,
when running in C mode.

Specifically its line 12 of comment.pgc:
// we also understand this style

It seems like ecpg should translate the comment from '//' to '/* */'
style, for the output .c file.

Thanks,
