[PATCH] file.c: open a file in binary mode in readfile()

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

O_TEXT is the default mode for fctrl's open() and on windows created
files, line endings are counted by fstat() as CR+LF adding an extra
byte for each line. the result from this is that, while the file still
can be read into a buffer, the read() return (ret) has a different
size compared to the previously allocated buffer, breaking at:

	if (ret == mem->size)

a solution is to open() the file in O_BINARY mode, which should
technically suppress the EOL translation.
