X-Git-Url: http://git.infradead.org/?p=ghostscript.git;a=commitdiff_plain;h=0513d1b9542d37e7134d36e49222b12ef469b722

Declare Ghostscript as _LARGEFILE64_SOURCE program, i.e. request transitional
interface to large file support. Check for mkstemp64() availability specially.

Subject: Replace non-standard function call fdopen64() with fdopen(). The former
X-Git-Url: http://git.infradead.org/?p=ghostscript.git;a=commitdiff_plain;h=dc01761c07d210974d829c35c33a8886c33b0488

Replace non-standard function call fdopen64() with fdopen(). The former
is not available on most platforms and not needed anyway because O_LARGEFILE
flag is set earlier in the code. Bug 689175.
