Doesn't compile on Debian 13

[ayshfm1]

I presume the c compiler has been updated and changed what were warnings into actual errors.

In order to make it compile the previous behaviour needs to be restored add the following to the MakeFile

I did these two

./console-client/pCloudCC/lib/pclsyn/Makefile
./console-client/pCloudCC/lib/poverlay_linux/Makefile

From this
CFLAGS=-Wall -Wpointer-arith -O2 -g -fno-stack-protector -fomit-frame-pointer -mtune=core2 -I../sqlite -DP_ELECTRON -fPIC

To this
CFLAGS=-Wall -Wno-error=implicit-function-declaration -Wno-error=incompatible-pointer-types -Wno-error=int-conversion -Wpointer-arith -O2 -g -fno-stack-protector -fomit-frame-pointer -mtune=core2 -I../sqlite -DP_ELECTRON -fPIC
