The problem was an INIT_LOCKS defined as nothing that sat between two ','
in 2.1.114. The base problem (that leads to the ugly hack with INIT_LOCKS
is that gcc-2.7.2.x crashes when empty structures are initialized with {}
inside certain structure/union nestings. egcs is fine, I posted two patches
to 2.1.114 that fix this. My second one looks like this stuff, but leaves
spinlock_t empty for recent compilers (as it was before).
