+Subject: [PATCH] curl: do bounds check using a double comparison
+
+The fix for this in 8661a0aacc01492e0436275ff36a21734f2541bb wasn't
+complete: if the parsed number in num is larger than will fit in a long,
+the conversion is undefined behaviour (causing test1427 to fail for me
+on IA32 with GCC 7.1, although it passes on AMD64 and ARMv7).  Getting
+rid of the cast means the comparison will be done using doubles.
+
+It might make more sense for the max argument to also be a double...
+
+Fixes #1750
+Closes #1749
