These were aimed at preventing the internals header from declaring
  a prototype for 'int UNITY_OUTPUT_CHAR(int);'. The second part fixed
  an omitted declaration in the tests caused by the first commit.
 Will replace the default behavior & add an option for this in next commit

 Prevent changes in core Unity from silently breaking Fixture

Fix #182, remove redundant function declarations (Thanks xor-gate!)

Fix unreachable code in Unity on fully covered switch statements

 Revert the previous commit. Add tests for extended enum cases.
 Fix crash due to accessing 'trait_names' array out of bounds.
 Adding an extra invalid value to the end of an enum causes '-Wswitch' flag
  to warn unless there is a switch default case - also enabled by '-Wall'.

 The clang compiler warns here with -Wunreachable-code
 The enum's switch statement covers all cases, so default is unused
 Leave the break in the code as a comment, to be more clear
 The history is this default case was added in f6bb7162 - compiler warning.
 Then the break was added in c6dc96f3.

Add Makefile with coverage target for Unity

 Unity is at 92% coverage now
 Run 'make -s' to see coverage information for unity.c
 Run 'make uncovered' to get missing lines output

100% code coverage for Unity Fixture

 Add tests for uncovered lines

Fix C89 warnings about variables at top of scope, enums, variadic macros

Clean up IgnoreTest function in Fixture

 Add extern UnityFixture in internals header. Add C89 target in Makefile
 clang will show these warnings but can suppress "//" with -Wno-comment.

 By removing the call to the Conclude function the code is simplified
  and doesn't depend on global state updates. Tests that are ignored
  after the testBody is called still output the right EOL.

Delete function call syntax from Spy detect macros

 This fixes #168. See that github.com issue for more discussion.
 Allows the tests to build when putchar() is defined as a macro
  with parenthesis around it, as in the ARM embedded gcc compiler.

Rename template for testing to be more fitting

UnityPrintFloat overflow fixes. (Thanks pacheco017!)

With a buffer long enough, no truncation should be neccesary to format floats.

Buffer length is user settable by defining UNITY_VERBOSE_NUMBER_MAX_LENGTH,
otherwise a sensible default is used based on desired precision.

See: http://stackoverflow.com/a/7235717

UnityPrintFloat() overflowed with some inputs (eg. FLT_MAX)

Fix additional primitive type conversion warnings on Linux

 Using gcc 4.8 on Ubuntu 14

Clean up int conversion warnings in Fixture

Delete unused Fixture internals functions for failure, ignore, & test counts

Bugfix - line numbers output by Fixture memory checks

Clean up int conversion warnings in core Unity using a 32-bit build

Move Makefile output to build/ directory in Fixture (Thanks jsalling!)

Permissions changed back from -x for testunity.c (Thanks jsalling!)

 Gets rid of warnings about extern with clang's -Weverything

 Turn on -Wconversion in Makefile, fix all warnings

 To expose warnings use -Wconversion -m32, and *not* -D UNITY_SUPPORT_64
 In 32-bit mode, the variable and parameter are the same width, so sign
  conversion is implicit. In 64-bit, implicit conversion is clean.
