Finished fixing floating point comparisons. We have streamlined how floats and doubles are checked, but we still can't compare them for equality directly. So we're directly testing for infinite and NaN before checking diffs. Also, we've officially decided that for testing purposes NaN shall equal NaN, +Inf shall equal +Inf, and -Inf shall equal -Inf. It's what most people expect during a test.

Fix warnings if you use UNITY_EXCLUDE_FLOAT

Bugfix Inf equals Inf

Test generator: scrub strings after comments

This fixes #220.

Removing strings from test files is still dangerous, but much
less likely to cause problems after this change to do the
removal after removing comments.

The bug could still manifest if a test file contains defines two
macros, one that contains a single quotation mark and then another
defined somewhere after it that contains a single quotation mark.
Everything in between the aforementioned quotation marks would
still be ignored after this commit, but that is an unlikely
scenario.

Add OSX to travis-ci build.

Print escapes for C strings

Merge build branch.

Switch to C language so we can specify operating systems. We have to install ruby 2.1 via rvm because the ruby interpreter on travis ci crashes when running rake ci, however that same version of ruby works fine on my local machine. This work around adds about 6 Minutes to the build and should be replaced as soon as possible to speed up builds.

Add check for linux and move initial CFLAG settings inside linux check. Add
CFLAGS specific to osx and clang to the existing osx/darwin check. Ignore clang warning about default on covered enum switch, look at pull #217 and pull #177 for more info about why that warning is ignored on clang. Ignore unknown clang options so that I don't have to change CFLAG settings elsewhere in the file, clang should just ignore options it dosen't know about.

Suppress output of FAIL messages that are expected during testing Unity itself. (This one makes me so happy! Thanks!)

 Changes from "\0x16" before, makes it easier to copy strings from output

 Works when using the putcharSpy, transparent without it

Make testunity.c failure output uniform

Fixture C89 comments

 Floats now pass Infinity == Infinity assertions

 Remove stdint.h from the C89 build due to -pedantic warnings from type
  'long long' and constants like UINTPTR_MAX = 18446744073709551615ULL

 Change the parameter of UnityPrintFloat from float to double (_UD)
 The call to snprintf uses implict default promotion to a double anyway

 Delete old comments from before math.h was the default isinf() method

 Refactor to use the same code everywhere for FloatWithin check
 Rename and fix a few tests for new behavior, infinity == infinity

Int width detection without sizeof

 CC always exists inside make so ?= doesn't assign to it

 The C preprocessor cannot use sizeof in #if etc.

 Covers the cases where infinity == infinity
