Hello,
First, I don't know if we can call this a bug, but only developpers can look in
this.
On 32-bit Linux armv7l(hardware : ODROID-U2), an application code that compiles
on x86_64, fails with the following errors :

g++ seems to be unable to use an int* pointer in get() because there's no
cppu_detail_getUnoType prototype that handles an int* . Next g++ gets confused
while trying to approximate things, between sal_Int32* and sal_uInt32* data
types.
The following patch, that adds a prototype of cppu_detail_getUnoType to handle
an int* parameter cures the problem, and compilation succeeds :

Is it the only way to solve the problem ?
Are there other tweaks I can do without having to patch unotype.hxx ?
Is it that on x86_64 cppu_detail_getUnoType never gets an int* as parameter
template ? Why , how ?
