GNU bison 1.75 solaris bug (with workaround).

[Rein Tollevik]

Bison 1.75 fails the following tests when compiled with the Sun Forte C
compiler:

Simple GLR Calculator.

 61: calc.at:480       FAILED near `calc.at:480'
 62: calc.at:482       FAILED near `calc.at:482'
 63: calc.at:483       ok
 64: calc.at:484       FAILED near `calc.at:484'
 65: calc.at:485       FAILED near `calc.at:485'
 66: calc.at:486       FAILED near `calc.at:486'
 67: calc.at:487       FAILED near `calc.at:487'
 68: calc.at:489       ok
 69: calc.at:491       ok
 70: calc.at:493       FAILED near `calc.at:493'
 71: calc.at:494       ok

The reason for the failures are that the struct yyltype defined in
data/glr.c ends up as en empty struct.  I don't have the ANSI C book
around, so I don't not sure whether this is allowed or not, but gcc
also gives a warning when run with -pedantic.

The small patch at the end fixes the problem.
