While remote.c works with "char *" buffers most of the time, other remote targets have binary-ish-er protocols, and choose to use "unsigned char" throughout, like e.g., remote-mips.c or remote-m32r-sdi.c. That results in -Wpointer-sign warnings in those targets, unless we add casts in calls to serial_write. Since serial_write is only concerned about sending raw host bytes out, and serial_ops->write_prim already works with "void *"/"size_t", a similar interface to the "write" or "send" system calls, I find it natural to change serial_write's prototype accordingly, avoiding the need for casts. Tested on x86_64 Fedora 17, and also by building x86_64-mingw32 and DJGPP/go32 -hosted gdbs. gdb/ 2013-04-19 Pedro Alves <palves@redhat.com> * ser-base.c (ser_base_write): Change prototype -- take 'void *' buffer and size_t size. Adjust. * ser-base.h (ser_base_write): Adjust. * ser-go32.c (cnts): Change type to size_t. (dos_write): Change prototype -- take 'void *' buffer and size_t size. Adjust. (dos_info): Print elements of 'cnts' as unsigned long. * serial.c (serial_write): Likewise. * serial.h (serial_write): Adjust. (struct serial_ops) <write>: Change prototype -- take 'void *' buffer and size_t size. Adjust.
