[GRASS5] r.binfer compile problem

[Markus Neteler]

Dear Michel,

it seems that you idea is perfect:
binfer.l

I added
%option lex-compat

at top of file. The yylineno def is now:

#ifndef sparc
#ifndef linux
int yylineno = 1;
#endif
#endif

Then it compiles on both platforms I have. BTW: flex is on
both, but one box is SuSe6.2, the other SuSe6.4 Linux distribution.

Thanks for your hint!

 Markus
