2017-04-15curl-compilers.m4: turn implicit function declarations into errorsMarcel Raad
This adds -Werror-implicit-function-declaration for GCC 2.95+ so that these errors are visible at the point where they occur instead of only at link time. Implicit function declarations are illegal in C99 and C++ anyway, and the same warning has been turned into an error for ICC in commit 3072c5b8a127057aa922b7c51051bbb4a630b091. Ref: https://gcc.gnu.org/onlinedocs/gcc-2.95.2/gcc_2.html#SEC8 Ref: https://curl.haxx.se/mail/lib-2017-04/0001.html Closes https://github.com/curl/curl/pull/1419
2016-11-07s/cURL/curlDaniel Stenberg
We're mostly saying just "curl" in lower case these days so here's a big cleanup to adapt to this reality. A few instances are left as the project could still formally be considered called cURL.
2016-06-21curl-compilers.m4: improve detection of GCC's -fvisibility= flagKamil Dudka
Some builds of GCC produce output on both stdout and stderr when --help --verbose is used. The 2>&1 redirection caused them to be arbitrarily interleaved with each other because of stream buffering. Consequently, grep failed to match the fvisibility= string in the mixed output, even though the string was present in GCC's standard output. This led to silently disabling symbol hiding in some builds of curl.

2013-09-27configure: use icc options without spaceDaniel Stenberg
The latest version(s) of the icc compiler no longer accept the extra space in the -we (warning enable), -wd (warning disable), etc. Reported-by: Elmira A Semenova Bug: http://curl.haxx.se/mail/lib-2013-09/0182.html
2013-09-07configure: improve CURL_CHECK_COMPILER_PROTOTYPE_MISMATCHDaniel Stenberg
The compiler test used a variable before it was assigned when it tried to see how it acts on a mismatching prototype, which could cause a false positive.
2013-03-08configure: use XC_LIBTOOL for portability across libtool versionsYang Tse
2013-01-20configure: autotools compatibility fixes - step IYang Tse
Fix proper macro expansion order across autotools versions for C compiler and preprocessor program checks.
2012-12-16configure: check if compiler halts on function prototype mismatchYang Tse
2012-11-16autoconf: don't force-disable compiler debug optionDaniel Stenberg
When nothing is told to configure, we should not enforce switching off debug options with -g0 (or similar). We instead don't use -g at all in that situaion and therefore allow the user's CFLAGS settings possibly dictate what to do.
2012-06-29curl-compilers.m4: remove -Wstrict-aliasing=3 from clangYang Tse
Currently it is unknown if there is any version of clang that actually supports -Wstrict-aliasing. What is known is that there are several that don't support it.
2012-06-26curl-compilers.m4: -Wstrict-aliasing=3 for warning enabled gcc and clang buildsYang Tse
2012-04-16curl-compilers.m4: -Wno-pedantic-ms-format for Windows gcc 4.5 buildsYang Tse
When building a Windows target with gcc 4.5 or newer and strict compiler warnings enabled use -Wno-pedantic-ms-format in addition to other flags.
2012-04-14headers: surround GCC attribute names with double underscoresJonathan Nieder
This protects from attribute names being defined by third party's code. Improvement: http://curl.haxx.se/mail/lib-2012-04/0127.html
2012-04-11build adjustments: CURL_HIDDEN_SYMBOLS no longer defined in config filesYang Tse
configure script now provides conditional definitions for Makefile.am that result in CURL_HIDDEN_SYMBOLS being defined by resulting makefiles when appropriate. Additionally, configure script option for symbol hiding control is now named --enable-symbol-hiding --disable-symbol-hiding. While still valid, old option name --enable-hidden-symbols --disable-hidden-symbols will be deprecated in some future release.
2011-08-08curl-compilers.m4: serial number bumpYang Tse
2011-08-08curl-compilers.m4: CURL_CONVERT_INCLUDE_TO_ISYSTEM adjustments:Yang Tse
Add CURL_CHECK_COMPILER as a requirement. Ensure macro does nothing unless GNU_C or CLANG compiler is used. This should allow usage of this macro in unforeseen placements.
