// Minimal stdint.h for the W65816 runtime. Standalone (does not

|
// include the host clang's stdint.h, which pulls in glibc headers
|
|
// and breaks the build). Sizes per the W65816 backend's view:
|
|
// char = 8 bits
|
|
// short = 16 bits
|
|
// int = 16 bits
|
|
// long = 32 bits
|
|
// long long = 64 bits
