Subject: libcdecl: Try unsigned __int64 for a 64-bit type.
X-Git-Tag: v1.3~17
X-Git-Url: https://git.draconx.ca/gitweb/cdecl99.git/commitdiff_plain/9786185611c072036751fdfcc1731158a0c2d20c

libcdecl: Try unsigned __int64 for a 64-bit type.

Windows compilers provide __int64 which may be available even if
long long is not.  While we don't yet build out of the box on
these compilers, let's try to avoid having the library ABI degrade
to 32-bit unsigned long when the build failures are fixed.
