Subject: Workaround gcc4.3 compiler error - disable pmm low mem allocations.
X-Git-Tag: rel-0.5.0~95

Workaround gcc4.3 compiler error - disable pmm low mem allocations.

For some unknown reason, the 16bit version of low memory expansion is
    confusing gcc4.3.  For now, just disable it as it isn't used in
    practice.
