new module 'pclose'

Anyone who calls popen() also calls pclose(). MSVC 9 does not have a 'pclose' function, but it has a '_pclose' function with the same semantics. 2011-09-17 Bruno Haible New module 'pclose'. * lib/stdio.in.h (pclose): New declaration. * lib/pclose.c: New file.

popen on MSVC

On MSVC 9, there is no popen() function, only _popen. The replacement code in lib/popen.c is not made for this situation: it gives compilation errors about F_SETFD. This fixes it. 2011-09-17 Bruno Haible popen: Support for MSVC. * lib/stdio.in.h (popen): Declare it if the syst

putenv on MSVC

The declaration of 'environ' in putenv.c:40 leads to a warning about "inconsistent DLL binding" and then later to a link error in test-unsetenv. This fixes it. 2011-09-17 Bruno Haible putenv: Support for MSVC. * modules/putenv (Depends-on): Add environ. * lib/putenv.c

math.h warnings on MSVC

On MSVC 9, there are warnings about redefined macros in gnulib's . This fixes them. 2011-09-17 Bruno Haible math: Avoid macro redefinition warnings on MSVC. * lib/math.in.h (ceilf, ceill, floorf, floorl, frexpl, ldexpl): Undefine before redefining. --- lib/math.in.h.o

An update of the documentation: Some functions are defined as macros with arguments in , without a function prototype. This is not allowed according to POSIX:2008 / System Interfaces / General Information / Use and Implementation of Interfaces

inet_ntop, inet_pton on MSVC

On MSVC 9, when compiling for Windows Vista or newer (cf. _WIN32_WINNT), declares an inet_ntop function. But the declaration uses __stdcall calling convention, which is incompatible with the normal C function call convention: $ cat foo.c #include char const * (*ptr2) (int, void const *, char *,

Re: Syntax checks in perl

Still, while I mostly prefer python to perl too these days, we have to consider that perl is already a pre-requisite for projects using autoconf, automake, and/or gnulib, so using perl would have the advantage of not adding another requirement to the maintainer toolchain. Certainl
